One year ago today, Reps. Fred Upton (R-Mich.) and Cliff Stearns (R-Fla.) — chairs of the House Energy Committee and Oversight Subcommittee respectively — sent a letter to Energy Secretary Steven Chu “seeking documents and information about a $535 million loan guarantee … awarded to Solyndra, Inc.”

That letter marked the beginning of an investigation that has since involved 31 more congressional letters, five congressional committee hearings, nine congressional committee staff briefings, 187,000 pages of documents from the administration, 72,000 pages of documents from Solyndra investors, testimony from five administration officials from three different departments, and a sworn committee interview with an Obama “bundler.”
