Waltz to Become U.N. Envoy; Rubio Steps In as Interim Security Adviser
WASHINGTON, D.C. – May 1, 2025 | Galaxy Tribune – President Donald Trump’s second term sees its first significant Cabinet shift, bringing notable changes to the national security landscape. Michael Waltz has been appointed as the next U.S. Ambassador to the United Nations, while Secretary of State Marco Rubio will temporarily take over Waltz’s responsibilities.
Trump Announces Waltz’s New Role
Waltz has been appointed as the United Nations Envoy, while Rubio will assume the role of Interim Security Adviser. President Trump confirmed the decision Thursday via his conservative social platform, praising Waltz’s years of service in the military, Congress, and the White House. The nomination now moves to the Senate, where Waltz will face confirmation hearings — a process that could raise difficult questions, especially following a recent communications mishap that made headlines.
Signal Chat Error Led to Rising Tensions
Waltz had faced criticism after accidentally adding a journalist to a confidential Signal chat with Trump’s senior advisers. The group had been discussing a sensitive military operation in Yemen targeting Houthi rebels. The slip-up triggered criticism and raised security concerns inside the administration. Despite ongoing speculation, Vice President JD Vance pushed back against claims that the Signal incident prompted Waltz’s reassignment. “If the president wanted to fire Mike over that Signal issue, he would’ve done it,” Vance said in an interview. “Mike’s been key to reforming the National Security Council, and we believe he’ll be even more effective representing our country at the U.N.” President Trump also defended Waltz earlier this spring, calling the incident a “lesson learned” and describing the adviser as “a good man.”
Rubio Juggles Dual Roles Amid Transition
Secretary of State Marco Rubio, spotted earlier speaking with senior White House staff during the National Day of Prayer event, is set to assume the role of acting national security adviser in addition to his current duties. The announcement came mid-briefing for State Department spokesperson Tammy Bruce, who reacted live to reporters. “I just found this out like you did,” Bruce admitted. She went on to call Rubio “a trusted leader who has been wearing multiple hats from day one.” Rubio’s appointment is not expected to be permanent, but he will retain both roles for the time being as the administration transitions.
What Comes Next for Trump’s Security Team
Waltz appeared at the White House Thursday morning for a televised interview but was absent from the afternoon’s prayer event. Just one day earlier, he participated in a Cabinet meeting where he praised Trump’s global leadership. While the administration navigates this high-profile personnel change, questions remain about the handling of secure communications and the broader implications of the Signal incident. President Trump, in a recent interview, joked about the ordeal: “Maybe don’t use Signal, okay? It may be widely used, but we should steer clear of it.” As the administration moves forward, Waltz’s confirmation process will be closely watched, and Rubio will continue managing U.S. foreign affairs, now paired with national security oversight.
