WASHINGTON — Republican lawmakers, escalating the political furor over the collapse of a solar equipment manufacturer that received a $528 million government loan, released excerpts from Obama administration e-mails on Wednesday suggesting that the White House pressed federal officials to wrap up their review of the loan quickly for political purposes.

In the e-mails, officials at the Office of Management and Budget expressed frustration that they were being put under time pressure to sign off on the loan to the company, Solyndra, two years ago so that Vice President Joseph R. Biden Jr. could announce its approval at a groundbreaking for a factory. The White House wanted an announcement that would show progress on job creation. The emails were first reported by the Washington Post and on the Web site of ABC News, in partnership with iWatch.

The disclosure became a focus of a House Energy and Commerce subcommittee hearing on Wednesday about the loan to Solyndra, which has developed into a political headache for the Obama administration. The administration used the company as a prime example of stimulus bill dollars creating “green jobs.” But Solyndra recently filed for bankruptcy protection and closed its factory, and its headquarters was raided by the Federal Bureau of Investigation, apparently in connection with the loan.

The bankruptcy filing and the raid “clearly show that the committee was more than justified in its scrutiny of the deal,” said the panel’s chairman, Representative Fred Upton, Republican of Michigan. “Why did the administration think Solyndra was such a good bet?”
