Vice President Joe Biden returns to Ohio on Thursday with a labor union visit in Columbus.

President Barack Obama's campaign says Biden will highlight his administration's support for the auto industry and the increase in Ohio manufacturing jobs. He will be at the Plumbers & Pipefitters Local on Thursday afternoon.

Biden's trip to the swing state will come three days after the president held a town hall in Cincinnati.

The pace of campaigning by the two sides in Ohio has been picking up in recent weeks. Republican challenger Mitt Romney has a town hall Wednesday in Bowling Green.

Meanwhile, former Florida Gov. Jeb Bush will promote Romney in southwest Ohio, starting with a stop at a Hamilton metals plant.
