Lara Trump, President-elect Donald Trump’s daughter-in-law, has resigned as co-chair of the Republican National Committee amid speculation that she could fill a possible Senate vacancy in Florida.

When she announced her resignation on social media, she said, “The job I wanted to accomplish is now accomplished,” citing the RNC’s successes in fundraising and voter turnout.

She has not indicated her next move, but some Trump allies have advocated for her to replace Sen. Marco Rubio, who was picked by the president-elect to be secretary of state.

If confirmed by the Senate as America’s top diplomat, Florida Gov. Ron DeSantis would choose a successor to serve out the remainder of Rubio’s six-year term, which ends in 2026.

In an interview with the Associated Press, Lara Trump said she is ready to take Rubio’s seat.

“It’s something I would seriously consider,” she said. “If I’m being completely transparent, I don’t know exactly what that would look like.”

Trump was elected co-chair of the RNC in March, hand-picked by her father-in-law – further evidence of his iron grip on the Republican Party.

Alongside her husband Eric and his older brother Don Jr., Lara Trump became one of the most prominent campaign representatives for Donald Trump’s run for the White House this year.

“It has truly been the honor of my life to serve as co-chair of the GOP during the most consequential election in American history,” she wrote on X, formerly Twitter. She also thanked her father-in-law, writing, “We are so proud of you and I am grateful that you have trusted me in this position.”

Several Republicans, including Sen. Rick Scott of Florida, have publicly supported her as Rubio’s successor in the Senate.

Last month, Maye Musk, the mother of close Trump ally Elon Musk, offered Lara Trump a strong Senate endorsement, writing on X: “The next senator for Florida should be (Lara Trump). The Senate is an old men’s club. We urgently need a smart, young, open woman who will reveal her secrets.

Elon Musk responded to the post: “Lara Trump is really great.”

The Florida Senate seat would be up for re-election in 2028.
