COLUMBUS, Ohio (AP) — Vice President Joe Biden is keeping up the attacks on Republican presidential hopeful Mitt Romney in Ohio.

Biden said in a speech Thursday at a Columbus union hall that Romney outsourced jobs while running the private equity firm Bain Capital, a claim the Romney campaign has rejected.

Biden also criticized the Republican for opposing President Barack Obama’s bailout of the auto industry.

The vice president was in Ohio to highlight the administration’s support for the auto industry and the increase in Ohio manufacturing jobs.

The pace of campaigning by the two sides in the state has been picking up in recent weeks.

Biden’s trip comes three days after the president held a town hall in Cincinnati. Romney made three stops in Ohio on Wednesday.
