OHIO TRUMP RALLY: FORMER PRESIDENT'S BACKING MAY ‘PROPEL VANCE TO VICTORY,’ INDICATE POWER OF HIS ENDORSEMENT

Trump's visit to the state comes after his endorsement of Ohio Senate candidate J.D. Vance. The former president backed Vance for the GOP Senate nomination in Ohio after top candidates jockeyed for his support for months. Rivals Mike Gibbons, Jane Timken and Josh Mandel — all advised and endorsed by at least some Trump-world regulars — sparred with Vance and each other about whose support for Trump was more genuine.

The event was slated to include speeches from Vance and Rep. Mike Carey, R-Ohio, as well as congressional candidates Max Miller and Madison Gesiotto Gilbert. The announced speakers have all received a Trump endorsement.

"Heading to Ohio for a big rally tonight, great crowd," Trump said in a statement before the event. "See you there!"
