Trump's visit will follow the scheduled appearances of the Democratic ticket ofHillary Clinton and Tim Kaine in Youngstownthis eveningand in Cleveland on Sunday. They then will speak at the Fort Hayes Metropolitan Educational Center in Columbus on Sunday. The beginning of the Clinton-Kaine event was moved up this afternoon to 2:45 p.m. -- nearly three hours earlier than the prior 5:30 p.m. start time.

Clinton and Kaine departed the Democratic National Convention in Philadelphia for an economy-centered bustour of Pennsylvania and Ohio.

Trump spoke in Toledo on Wednesday night, his campaign mindful of the fact that no Republican ever has won the White House without carrying Ohio.

The fight for Ohio's electoral votes will be fierce, with both tickets and their surrogates flooding the state ahead of the fall election. Central Ohio will be a particular key in who wins the state.
