Republicans on the House Energy and Commerce Committee today called for a subpoena of White House records regarding the half-billion dollar taxpayer loan guarantee of Solyndra, a move Rep. Diana DeGette, the ranking Democrat on the panel, blasted as “an act of irresponsible partisanship.” “In my 15 years on this subcommittee, we have forged a strong bipartisan tradition of thorough and meaningful investigations. That could have been the case with the Solyndra investigation,” DeGette said today at a subcommittee meeting on oversight and investigations.
