 The delegates formally nominated Trump as their 2024 presidential candidate shortly after he announced Ohio Senator J.D. Vance as his running mate. Mick Kennard has more on him. Vance was first elected to the Senate in 2022 after receiving an endorsement from Trump in a contested Republican primary. Vance, who penned his memoir Hillbilly Elegy about life in Appalachia, once described himself as a never-Trumper. But when he was running for Senate, Vance said he regretted those comments and was a supporter of Trump.
