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

Waltz was one of President Trump’s most visible surrogates during the 2024 campaign, leading the 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 Wall Street Journal first reported that Waltz was offered the role. Fox News Digital has contacted 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 location on the east coast of Florida, so it is very unlikely that it will fall into Democratic hands. But replacing an MP is a process that can take several weeks.

Republicans are on track to win the House of Representatives by only a narrow margin, so reducing their numbers in Congress could fuel delays in the first 100 days of Trump’s own agenda.

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 member to be tapped for an administrative role after House GOP Conference Chair Elise Stefanik, R-N.Y., accepted Trump’s nomination as ambassador to the United Nations earlier on Monday.

Both Stefanik and Waltz serve on the House Armed Services Committee and the House Permanent Select Committee on Intelligence.

“I am truly honored to earn President Trump’s nomination to serve in his Cabinet as U.S. Ambassador to the United Nations. During my conversation with President Trump, I expressed how deeply humbled I am to accept his nomination and that I look forward to earning the support of my colleagues in the U.S. 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 has 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 recovery. of America’s First Peace Through Strong Leadership on the World Stage on Day One at the United Nations.”

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

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