WASHINGTON (AP) — The Libertarian Party on Sunday nominated party activist Chase Oliver for president, rejecting former President Donald Trump and Robert F. Kennedy Jr. after they each spoke at the party’s convention.

Third parties have rarely been competitive in U.S. presidential elections and the Libertarian candidate four years ago won 1% of the vote. But the party’s decision is getting more attention this year due to the rematch between Trump and Democratic President Joe Biden, which could hinge again on small vote margins in a handful of contested states.

“We did it! I am officially the presidential nominee,” Oliver posted Sunday on X, formerly Twitter. “It’s time to unify and move forward for liberty.”

Trump appeared Saturday night in Washington at the convention to give a speech that was repeatedly booed by many in the room. It did not pay off with the endorsement he requested, though his Republican allies on Sunday praised him for choosing to go before an unfriendly crowd.
