Romney has leveled the critique before about a federal loan guarantee to the solar panel manufacturer Solyndra, including once when he visited the firm's shuttered headquarters. The corporation went bankrupt after receiving a $535-million loan guarantee approved by the Obama administration.
On Tuesday, he also mentioned Fisker, a manufacturer of electric cars. And the Republican National Committee began a similar attack built around former California Controller Steve Westly, a major Obama bundler whose portfolio includes Tesla Motors, which the RNC says has received hundreds of millions of taxpayer dollars.
