GOP Rep. Mike Waltz became Trump’s national security adviser

Rep. Mike Waltz, R-Fla., has been offered the role of national security adviser in the next Trump administration, a source confirms to Fox News Digital.

Waltz has been one of President-elect Trump’s most visible surrogates during the 2024 campaign, spearheading military outreach and helping with the Veterans For Trump coalition.

The Florida congressman is the first retired Green Beret to serve in Congress and had previous administration experience as a policy advisor to former Defense Secretaries Donald Rumsfeld and Robert Gates.

The The Wall Street Journal first reported that Waltz was offered the role. Fox News Digital reached out to the White House for comment.

However, elevating a House lawmaker to the administration could complicate Republicans’ ability to control the chamber.

Waltz is in a safe red seat on the eastern Florida coast, so it is highly unlikely to fall into Democratic hands. But replacing a member of Parliament is a process that can take several weeks.

Republicans are on track to win the majority in the House of Representatives by a narrow margin, so cutting their numbers in Congress could cause delays to Trump’s own first 100-day agenda.

House Majority Leader Steve Scalise, R-La., speculated on Fox & Friends last week that Republicans would win by about four to six seats.

Waltz is the second House lawmaker tapped for an administration role after House GOP Conference Chairwoman Elise Stefanik, RN.Y., accepted Trump’s nomination to be ambassador to the United Nations earlier Monday.

Both Stefanik and Waltz are members of the House Armed Services Committee and the House Permanent Select Committee on Intelligence.

“I am truly honored to win President Trump’s nomination to serve in his Cabinet as United States Ambassador to the United Nations. During my conversation with President Trump, I shared how deeply humbled I am to accept his nomination and that I look forward to win the support of my colleagues in the United States Senate,” Stefanik said in her statement accepting the nomination.

“The work ahead is enormous as we see anti-Semitism skyrocket coupled with four years of catastrophically weak American leadership that significantly weakened our national security and diminished our standing in the eyes of allies and adversaries alike. I stand ready to promote President Donald J . Trump’s restoration of America First peace through force leadership on the world stage on day one at the United Nations.”

Like Waltz, Stefanik’s upstate New York district is a safe Republican stronghold.

The NSA role does not require Senate confirmation, but the UN ambassador role does.
