Republicans have pounced on last year’s Solyndra bankruptcy, arguing that the administration missed a series of red flags that hinted at the company’s financial problems. They’ve also alleged that the administration approved the loan in 2009 to please Obama’s campaign donors.

The House Energy and Commerce Committee’s year-long investigation into the Solyndra loan guarantee has not uncovered evidence of political favoritism. But it has unearthed documents that are likely embarrassing and potentially politically damaging for the White House, including some that show officials questioning the wisdom of issuing the loan guarantee.

The White House sent another 432 pages of documents to Republicans on the House Energy and Commerce Committee on Friday in response to a November subpoena for all Solyndra communications.
