Mitt Romney’s campaign is out with a new video that takes aim at White House support for the now-bankrupt solar company Solyndra and other taxpayer-supported green energy companies.

The video released Tuesday revives GOP attacks on green energy programs and adds to the political thrust-and-parry between Romney and President Obama over their records on economic stewardship.

“You’ve heard of Solyndra. They took $535 million in taxpayer loan guarantees and went bankrupt. But that’s not even half the story,” says the video, pointing to other companies that have hit financial headwinds after receiving federal loan guarantees or grants.

“Obama is giving taxpayer money to big donors. And then watching them lose it,” the ad states.
