Ten Republicans are vying to replace former Rep. Matt Gaetz in a crowded primary election kicking off on Tuesday.

Vance officially resigned from the post Friday. The next senator will be chosen by Republican Governor Mike DeWine, who under Ohio law will be tasked with appointing a replacement until 2026, when a special election will determine who will serve in the role until the term expires in 2029.

Donald Trump had selected Vivek Ramaswamy, a hedge fund and pharmaceutical executive, to lead the commission on government efficiency alongside billionaire Elon Musk. He ran for president in 2024 and later endorsed Trump.
