The Treasury Department’s March 2009 review of the Energy Department’s $535 million loan guarantee for the solar company Solyndra was “rushed” and it’s not clear whether Treasury’s concerns were fully addressed, the department’s internal watchdog concludes in a new report.

The Treasury report details quick reviews just days before the Energy Department (DOE) issued a press release announcing conditional funding for Solyndra, the California solar panel company that went bankrupt last September.
