Trump's national security adviser nominee, Waltz, resigns from the House, reducing the GOP majority.

On Monday, Rep. Mike Waltz, R-Fla., left Congress to become President-elect Trump's national security adviser, a move that had been anticipated for some time.

On Inauguration Day, Waltz had informed Planet Chronicle of his intention to resign, which reduced the Republican House majority to 218–215.

Waltz announced his resignation from the U.S. House of Representatives, effective January 20th, 2025, as he prepares to assume his duties as National Security Advisor to the president-elect, Donald J. Trump.

"I plan to complete my term in the 118th Congress and be officially sworn in. Additionally, I have informed Governor Ron DeSantis of my intention to resign."

A special election to replace Waltz will be held in April.

The announcement of his departure from the House coincides with the ongoing struggle among Republicans in the chamber to maintain unity due to disagreements over government spending, loyalty to Trump, and ideological differences.

During the election of House Speaker Mike Johnson in January and the massive spending bill in December that narrowly averted government shutdown, the divisions were evident.

Trump appointed Waltz, a former Green Beret who previously worked in the White House and Pentagon, as his national security adviser in the fall of 2024.

Trump commended Waltz's 25+ years in the Army Special Forces, highlighting his multiple combat deployments and four Bronze Stars, including two with Valor.
