Summary
Mike Waltz served as the U.S. National Security Advisor during the Trump administration, playing a prominent role in shaping the administration’s foreign policy and national security strategies, particularly with a hawkish approach toward Iran and other security threats. His tenure was marked by significant media presence and influence among conservative policymakers, but it ended amid controversy and internal White House tensions. Waltz’s departure coincided with a broader reshuffling of national security leadership, including the unprecedented consolidation of power by Senator Marco Rubio, who assumed multiple senior roles following Waltz’s exit.
A notable controversy during Waltz’s time as National Security Advisor involved his use of a modified version of the Signal messaging app for official communications on government devices. Photographic evidence revealed that Waltz employed software from TeleMessage, a company that adds archiving capabilities to messaging apps, raising concerns about the security and confidentiality of sensitive military discussions. This issue was amplified when Waltz mistakenly included *The Atlantic* journalist Jeffrey Goldberg in a Signal group chat containing classified military plans, leading to political embarrassment and scrutiny over information security protocols within the White House.
The leaked Signal group chat also featured senior officials such as Secretary of State Marco Rubio and Defense Secretary Pete Hegseth, who faced criticism for sharing sensitive operational details about potential military strikes against Yemen’s Houthi rebels. While the White House maintained that Signal was an approved communication tool on government phones, Democrats renewed calls for accountability, particularly targeting Hegseth for his role in compromising classified information.
Waltz’s departure to a less influential post as U.S. Ambassador to the United Nations was widely viewed as a demotion and underscored the complexities of managing sensitive information and personnel within the Trump administration. Although President Trump publicly praised Waltz’s service, internal dissatisfaction and security lapses during his tenure highlighted the challenges facing the administration’s national security apparatus in its final months.
Background
Mike Waltz served as the U.S. National Security Advisor during the Trump administration, playing a key role in shaping the administration’s foreign policy and national security strategies. Known for his hawkish stance, Waltz was regarded by many Republican conservatives as a crucial figure capable of steering President Trump toward more aggressive military options, particularly regarding Iran. Despite his visibility in the media, including frequent appearances on Sunday news shows and Fox News, Waltz’s presence seemed to diminish in the weeks leading up to his departure amid rumors that White House Chief of Staff Susie Wiles was seeking a replacement for him.
Waltz’s tenure ended as he was nominated for the role of U.S. Ambassador to the United Nations, a position that, while prestigious, carried less influence compared to his role as National Security Advisor. His nomination was expected to face a contentious confirmation process, especially given prior controversies surrounding his handling of sensitive information. Earlier in the administration, Trump had considered Rep. Elise Stefanik for the UN post but rescinded her nomination due to concerns about weakening the Republican majority in the House.
One notable incident during Waltz’s time as National Security Advisor involved the use of the messaging app Signal for official communications. A photograph captured by Reuters photojournalist Evelyn Hockstein showed Waltz’s phone displaying a PIN verification message that was inconsistent with the standard Signal app, suggesting the use of a third-party software, TeleMessage, which archives messaging data. This raised questions about the security and confidentiality of sensitive military discussions, especially after Waltz mistakenly included a journalist in a Signal group chat that contained classified military plans, resulting in political embarrassment and calls for accountability.
The Signal group chat reportedly included several senior officials such as Secretary of State Marco Rubio, Director of National Intelligence Tulsi Gabbard, and Trump’s special envoy to the Middle East, Steve Witkoff. Rubio himself was undergoing a significant expansion of responsibilities, holding four roles simultaneously within the administration, including Secretary of State and National Security Advisor—an unprecedented consolidation of power since Henry Kissinger’s tenure half a century earlier.
Despite these controversies, President Trump publicly expressed confidence in Waltz’s service, praising his dedication from his military service to his time in Congress and at the White House. However, internal tensions were evident, as Waltz faced criticism for not defending his staff more vigorously amid dismissals of senior directors within the National Security Council who had conservative policy backgrounds. Trump’s preference for conducting sensitive conversations in secure environments became clear in cabinet meetings, signaling his dissatisfaction with the management of classified communications.
Revelation of Secret App Usage
During Mike Waltz’s tenure as National Security Advisor, it was revealed that he used a modified version of the Signal messaging app on government devices. A photo taken by Hockstein showed a PIN verification message differing from the standard Signal app interface, indicating Waltz was utilizing software from TeleMessage, known for adding archiving capabilities to cloned versions of messaging applications. This discovery raised concerns as sensitive military information had been shared in message threads involving Waltz, including confidential plans for a military strike on Yemen’s Houthi rebels, involving participants such as Waltz, Senator Marco Rubio, and Defense Secretary Pete Hegseth.
Despite the controversy, the White House maintained that Signal was an approved communication tool for government use, with spokeswoman Anna Kelly emphasizing its official status on government phones. President Trump reportedly expressed dissatisfaction with the handling of sensitive conversations after a Cabinet meeting where Waltz was present, underscoring the importance of secure communication settings.
The revelations surfaced amidst Waltz’s impending move to a less influential position as U.S. Ambassador to the United Nations, a transition viewed as a demotion compared to the National Security Advisor role. This change coincided with a broader reshuffling in the administration, where key figures such as Rubio held multiple significant roles, including National Security Advisor and Secretary of State.
Circumstances of Disclosure
The disclosure of sensitive information involving Waltz arose from a security lapse linked to the use of a modified Signal app provided by TeleMessage, which enables archiving capabilities on cloned messaging apps. This was uncovered after a photograph posted by staffer Hockstein showed a PIN verification message different from the standard Signal app, indicating the use of this specialized software.
The incident gained significant attention after journalist Jeffrey Goldberg from *The Atlantic* was inadvertently included in a Signal group chat where sensitive military plans were discussed. This breach became a political embarrassment and was anticipated to be a critical issue during Waltz’s confirmation hearings for a United Nations post. Goldberg had previously contacted the Trump campaign regarding a critical story about the president’s attitude toward wounded service members, leading the campaign to enlist Waltz’s help as a national security surrogate to counter the narrative.
President Trump’s decision to remove Waltz from his role was reportedly influenced by the group chat breach. Although Trump disapproved of Defense Secretary Pete Hegseth’s poor judgment in sharing classified Yemen war plans within the chat, he did not seek Hegseth’s dismissal. Instead, Waltz bore the brunt of the fallout, partly due to questions about how Goldberg was granted access to the group. Waltz’s departure marked the first senior exit during Trump’s second term and was perceived as a significant loss for Republican hawks advocating for assertive military policies. Prior to his removal, Waltz had been a prominent media presence but his visibility diminished amid speculation that Chief of Staff Susie Wiles was searching for his replacement. Despite the controversy, the White House maintained Signal was an approved government app.
Impact and Consequences
Michael Waltz’s departure marked a significant shift within the Trump administration, particularly for Republican hawks who regarded him as a key advocate for more aggressive military strategies, including toward Iran. His exit was followed by Secretary of State Marco Rubio assuming multiple roles simultaneously, including interim National Security Advisor, consolidating considerable influence.
The exposure of confidential military plans on the Signal app—used by Waltz, Rubio, and Defense Secretary Pete Hegseth—sparked controversy. Hegseth faced renewed calls for removal after sharing sensitive information about a potential strike on Yemen’s Houthi rebels via the chat group. This incident raised concerns about operational security and appropriateness of communication platforms for classified discussions.
Within the White House, fallout was palpable. President Trump expressed displeasure over sensitive conversations outside secure environments, signaling a tightening of protocols after the leaks. Though public statements conveyed confidence in Waltz, internal dynamics suggested unease, including dissatisfaction among National Security Council staff about Waltz’s perceived lack of vigorous defense of his team.
Waltz’s role extended beyond security; he assisted the Trump campaign in countering critical media stories, such as those on the president’s treatment of wounded service members. His transition to a potential United Nations ambassador role was met with skepticism about its influence, suggesting a diminution of his direct impact on national security policy. The sequence underscored challenges in managing sensitive information and personnel roles in the Trump White House.
Responses and Statements
The revelation that Waltz invited The Atlantic Editor-in-Chief Jeffrey Goldberg to a Signal chat discussing sensitive military plans drew significant attention and criticism. The chat included potential airstrikes on Houthi targets in Yemen and involved senior officials such as Defense Secretary Pete Hegseth and Senator Marco Rubio. Waltz faced backlash for mistakenly adding a journalist to the group, an error likely to impact his Senate confirmation hearings for the United Nations ambassador post.
A White House spokeswoman, Anna Kelly, defended Signal as “an approved app for government use and is loaded on government phones”. Democrats sharply criticized Hegseth for sharing sensitive military attack plans in the chat, renewing calls for his removal. President Trump disapproved of Hegseth’s judgment but did not favor dismissing him due to the political capital invested in his confirmation.
Following Waltz’s departure, Trump appointed Secretary of State Rubio as interim replacement, surprising some State Department officials. Rubio’s assumption of multiple high-level roles, including National Security Advisor and acting USAID administrator, marked a concentration of power not seen since Henry Kissinger’s era half a century ago. Trump praised Waltz’s service and expressed confidence he would continue to serve with commitment in his new position.
Internally, some National Security Council staff expressed dissatisfaction with Waltz’s perceived lack of strong defense for his staff amidst dismissals and controversies. Waltz’s move to the UN ambassador role was viewed as a loss for Republican hawks advocating aggressive military policies, particularly towards Iran. The administration appeared to treat the UN post as a lower priority compared to Waltz’s previous role.
Investigations and Inquiries
In early 2024, an internal investigation was launched after revelations that Waltz used a modified Signal app equipped with archiving capabilities, not standard on government devices. The altered PIN verification message in a photo by Hockstein indicated Waltz employed software from TeleMessage, raising concerns about handling sensitive communications.
The investigation intensified after Waltz mistakenly included a journalist in a private group chat discussing confidential military plans, specifically airstrikes against Houthi targets in Yemen. This breach was a significant political embarrassment during his Senate confirmation hearings for the U.N. ambassador role. Participants included Secretary of State Rubio and Defense Secretary Hegseth.
Democrats condemned Waltz’s conduct and renewed calls for Hegseth’s removal amid concerns over security lapses. Despite controversies, the White House maintained Signal was an approved government app installed on official phones.
Further scrutiny arose from Waltz’s role as a national security surrogate during the Trump campaign, countering negative media coverage about the president’s treatment of wounded service members, highlighting the blending of political strategy and national security functions.
The fallout contributed to tension within the National Security Council. Some staffers were frustrated Waltz did not vigorously defend his team during disputes. President Trump publicly expressed confidence but preferred discussing sensitive topics in more secure settings following these events.
Waltz’s impending confirmation battle for the U.N. ambassador position was contentious, with sources indicating Trump did not regard the U.N. role as a priority. This contrasted with Waltz’s previous position managing critical security issues.
Public and Media Reaction
The revelation that Waltz and other senior officials used Signal to discuss sensitive military plans prompted significant public and media attention. White House spokeswoman Anna Kelly emphasized Signal was approved for government use and pre-installed on phones. However, exposure of confidential discussions, including a military strike plan targeting Yemen’s Houthi rebels, triggered criticism from Democrats and intensified scrutiny of classified information handling.
Democratic lawmakers condemned Defense Secretary Hegseth for sharing sensitive military details in the same Signal chat, renewing calls for his removal. Waltz faced criticism for mistakenly adding a journalist to the chat, a focal point during his confirmation hearings for the UN post.
Media coverage detailed how The Atlantic’s Editor-in-Chief Jeffrey Goldberg was invited to the Signal chat by Waltz shortly before Waltz’s White House departure. This occurred as the campaign attempted to counter a critical story about Trump’s attitude toward wounded service members, with Waltz serving as a national security surrogate. The incident fueled concerns about internal communications and safeguarding sensitive information.
Within the administration, the dismissal of Waltz and other senior directors with conservative backgrounds left some colleagues perplexed and upset, especially regarding Waltz’s perceived lack of defense for his staff. Observers noted that while Waltz’s forthcoming UN role would be less influential, the nomination was expected to provoke a contentious Senate confirmation battle.
Legacy and Aftermath
Mike Waltz’s tenure as National Security Advisor was marked by controversy over communication apps within the White House. A photo by Reuters photojournalist Evelyn Hockstein revealed Waltz’s phone displaying a PIN verification message inconsistent with the standard Signal app interface, indicating use of TeleMessage software, which enables archiving on cloned messaging apps. This came amid concerns about secure communications, especially after confidential military plans about strikes in Yemen were shared in a Signal chat including Waltz, Senator Rubio, and Defense Secretary Hegseth.
Waltz’s departure followed weeks of diminishing visibility and speculation about his replacement, reportedly led by Chief of Staff Susie Wiles. Although Trump publicly expressed confidence in Waltz, his preference for conducting sensitive conversations in more secure settings signaled underlying dissatisfaction. Colleagues noted Waltz’s inability to more forcefully defend his staff amid these issues caused unrest within the National Security Council.
The aftermath affected administration power dynamics. Waltz’s anticipated move to the UN ambassador post was seen as a demotion with far less influence than his previous role overseeing U.S. national security matters. Senator Rubio assumed an unprecedented combination of roles including Secretary of State and National Security Advisor, a concentration of power not seen since Kissinger’s era half a century ago. This surprised State Department officials and highlighted shifting priorities.
Democrats criticized the handling of security protocols and called for removal of Defense Secretary Hegseth due to his involvement in sharing sensitive military information in the Signal chat. Despite criticisms, White House spokespeople defended Signal as an approved government app, downplaying concerns about messaging practices during Waltz’s tenure.
