Lara Trump will step down as co-chair of the Republican National Committee. One of her potential next steps is replacing Florida Sen. Marco Rubio, whom Donald Trump tapped to be the next secretary of state. If Rubio is confirmed, Florida Gov. Ron DeSantis would choose who takes the seat through the remainder of Rubio’s term, which expires in 2026. Lara Trump tells The Associated Press in an interview that filling a Senate vacancy is something she'd seriously consider. Elected as RNC co-chair in March, Lara Trump was a key figure in the Republicans retaking the White House and control of the Senate while maintaining a narrow House majority.
