Karoline Leavitt, a 25-year-old former aide to the Trump White House, has won the Republican primary for a key swing U.S. House district in New Hampshire, beating Matt Mowers, a former state GOP chair and candidate for the seat in 2020.

Leavitt, a first-time candidate, struggled during the initial days of the campaign but soon outdistanced nine other GOP candidates in New Hampshire’s 1st Congressional District. She won with 15,290 votes, 33.4 percent, leading Mowers who got 11,650 votes.
