President Donald Trump’s abrupt dismissal of National Security Adviser Michael Waltz capped a months-long erosion of trust inside the West Wing, fueled by policy disagreements and culminating in a controversial use of the encrypted messaging app Signal. As reported by The Washington Post, the final catalyst for Waltz’s removal came after he included a journalist in a private Signal group chat that discussed sensitive national security matters — a breach that became known inside the administration as “Signalgate.”
But according to senior officials who spoke to The Washington Post, trouble had been brewing well before the March messaging mishap. Tensions escalated following Waltz’s direct coordination with Israeli Prime Minister Benjamin Netanyahu ahead of a February Oval Office meeting. Waltz reportedly advocated a military strike against Iran — a position that clashed with Trump’s growing preference for diplomacy in the region.
“Waltz wanted to take U.S. policy in a direction Trump wasn’t comfortable with,” said one source familiar with the matter, adding that the president felt blindsided by the depth of Waltz’s cooperation with Israeli officials. Although Netanyahu’s office confirmed a meeting took place, it denied the characterization of “intensive contact.”
Trump, who has increasingly sought to surround himself with loyalists over policy experts, tapped Secretary of State Marco Rubio to serve as acting national security adviser. Rubio, seen as more adaptable to Trump’s evolving foreign policy views, is expected to maintain a caretaker role, signaling a potential sidelining of the traditional National Security Council (NSC) structure.
The shift comes amid broader efforts by Trump to centralize power and strip away bureaucratic institutions that were mainstays during his first term. According to insiders, the president has grown more confident in his own instincts and is less reliant on traditional advisors. “You work for the president of your country, not a president of another country,” one adviser said, drawing comparisons to historical breaches of presidential trust.
Despite the controversy, Waltz will remain in government. Trump has nominated him to serve as ambassador to the United Nations, a move some interpret as a graceful exit rather than a full dismissal. Still, the change underscores the president’s desire for ideological alignment over experience in his top ranks.
The drama surrounding Waltz’s departure reveals a deeper recalibration inside the Trump administration, where loyalty and message discipline are prioritized over dissent and independent strategy. One White House official noted that the decision ultimately came down to Trump’s own judgment: “With decisions like this, it’s him.”
