The video features a speech Vice President Joe Biden made in Maumee, Ohio during the 2008 campaign, in which he lambasted Republicans for allowing the debt to rise to $8 trillion at the time. It now stands at more than $15 trillion.

The RNC will also host a conference call Friday with Rep. Tim Murphy of Pennsylvania, who's also expected to target Obama over the debt.

On the second day of his trip, Obama will again start in Ohio in the city of Poland, then cross the border into Pennsylvania and hold a campaign event in Pittsburgh.

The president was last in the Keystone State in mid June, when he held three fund-raisers in one day in Philadelphia. His wife, Michelle, also ventured to the city in early June and fired up a Philly crowd, urging them to turn out for her husband in November.

CNN rates Pennsylvania as a state leaning toward Obama. However, when Romney stopped there on his own bus tour, he predicted a victory later this year.

"I've got news for you," Romney told a crowd at a campaign stop in Cornwall. "I am going to win Pennsylvania!"

A separate Quinnipiac survey released last week, however, indicated the president had a slight margin over Romney, 45% to 39%. Obama carried the state in 2008 with 55% of the vote.

Both campaigns have aired state-specific ads in Ohio and Pennsylvania. And according to a Republican ad buying source, the Obama campaign will spend more than $6 million on ads in Ohio during the month of July, with more than $900,000 going toward Pennsylvania. The amounts are part of a $25 million ad buy the campaign purchased this month.

The Romney campaign has not bought air time for the entire month yet but is already spending over $7.5 million through July 10.

While the president will end his tour Friday, he heads back out to another swing state next week, returning to Iowa for a campaign event in Cedar Rapids.
