LOVELAND, Ohio (AP) — Kentucky U.S. Sen. Rand Paul will campaign in Ohio with a Republican candidate in the May 8 Senate primary.

Paul joins Mike Gibbons on Thursday afternoon in the Cincinnati suburb of Loveland.

Gibbons is a Cleveland investment banker who helped raise funds for Republican Donald Trump’s presidential bid. The president is backing U.S. Rep. Jim Renacci. Gibbons calls himself the "conservative outsider" in the race and has a campaign commercial that says he will help Trump "drain the swamp" in Washington.

There are three other GOP candidates in the Senate primary, with the winner taking on two-term incumbent Democratic Sen. Sherrod Brown this fall

Paul was among the early GOP presidential challengers in 2016 before he dropped his bid and won re-election to his second Senate term.
