The House adjourned about three hours ago, but GOP lawmakers, outraged that Speaker Nancy Pelosi (D-Calif.) and the Democrats went home for five weeks without allowing a vote on offshore drilling, have refused to leave the floor. Even though C-Span can't show you what's going on (C-Span is prevented from showing what's happening on the floor when the House is out of session), Republicans are holding an unprecedented session on the House floor. They have brought in dozens of their members, who are walking up and down the aisles making speeches. They have packed the floors and galleries with staffers. When Capitol Police tried to remove reporters from the gallery, Republicans stopped it from happening. The crowd has repeatedly broken out in chants of "Vote, vote, vote!" There's several dozen Cub Scouts sitting on the House floor in seats normally occupied by members.
Update - A GOP staffer just informed me that post-adjournment protests by the minority party are not unprecedented. The Democrats did it back in 1995, when the Republicans were in control. Democrats placed a big photo of then-Speaker Newt Gingrich (R-Ga.) wearing a diaper in the Speaker's chair. Republicans note they are being more respectful this time.
Rep. Kevin Brady (R-Texas), who was on a place headed home, headed back to the Capitol, walking onto the floor dragging his luggage. He got a standing ovation.
Rep. John Shadegg (R-Ariz.) called it a "new Boston Tea Party!"
Rep. Mike Pence (R-Ind.) said he was "not leaving until we call this Congress back into session and vote for energy independence."
Rep. Tom Cole (Okla.), chairman of the National Republican Congressional Committee, said the dimly lit chamber is a "vision of the future by the Democrat Party - the lights are out, there's no power, and the air conditioning is gonna go off soon."
