As well they should as there is a DOJ investigation ongoing:

Top executives from a bankrupt California solar energy company pleaded the Fifth Amendment more than a dozen times Friday in a congressional hearing that went nowhere but gave members the opportunity to pose dozens of questions about the loss of a half billion dollars in government loans.
Solyndra Inc. CEO Brian Harrison and the company’s chief financial officer, Bill Stover, had notified the House Energy and Commerce Committee they were going to invoke their Fifth Amendment right to decline to testify to avoid
That didn’t mean lawmakers didn’t have questions for the executives, leading to complaints from committee Democrats that House Republicans were badgering the witnesses.
The Supreme Court has ruled it’s considered prosecutorial misconduct when the government calls witnesses with the flagrant intent of questioning them to invoke their Fifth Amendment, said Rep. Henry Waxman, D-Calif.

Oh, please. Now Waxman is complaining? This is the same grandstanding from the GOP that we saw from Dems when they brought banking execs in to testify. It’s all a show.

This is yet another example of Congress, both Republicans and Democrats, shirking their oversight responsibilities. This deal stunk from day one (just check the PG archives) and nobody in Congress said anything. Now, rather than say investigate the other companies in the DOE portfolio, the GOP is going for the cheap soundbite.

And if any Republican tries “Solyndra executives lied to us” like Dems pulled during the Iraq war, it’s probably best that you resign now as it shows you’re not smart enough for the position you currently hold at our expense.
