Obama claims Romney's plan will encourage companies to outsource more jobs

NATIONAL -- The presidential election is just under four months away and the race is heating up with both sides attacking each other on the economy.

President Obama attacked Romney over his business dealings and tax returns.

The Obama campaign says that under Romney's watch, Bain Capital, the private equity firm he founded, outsourced jobs.

"Governor Romney's plan would actually encourage companies to shift  more of their operations to foreign tax havens, creating 800,000 jobs in those other countries," Obama said.

Romney says the president is diverting voters' attention from the economy.

Even though Romney took a break from the campaign trail today, he got help from a senator who's on the former governor's short-list to be his running mate in the fall.

"The President said back in 2008 when you're out of fresh ideas you turn to stale tactics of attacking your opponent and unfortunately, that's what he's been doing," Sen. Rob Portman of Ohio  said.

Fellow Republicans are also questioning Romney's refusal to release more tax returns.
