I saw this happening on C-Span, but wasn't sure exactly what I was seeing. Went to Senator Reid's website, still no clue. This much I can tell you:

Senator Harry Reid just gave an incredible speech on the floor of the Senate, the gist of which was a demand that the Republican majority agree to commence on the second section of the promised SSCI report on how this administration's handling and pursuit, or non-pursuit, of intelligence resulted in the American people finding themselves invading Iraq in early Spring of 2003.

He then demanded a closed session, Durbin seconded, and despite a fevered meeting between Frist et al at the back of the chamber, Senator Reid had caught them off-guard, and the Senate is now meeting in closed session.

Here's part of what the AP has so far:

WASHINGTON - Democrats forced the Republican-controlled Senate into an unusual closed session Tuesday, demanding answers about intelligence that led to the Iraq war. Republicans derided the move as a political stunt.

In a speech on the Senate floor, Democratic leader Harry Reid said the American people and U.S. troops deserved to know the details of how the United States became engaged in the war, particularly in light of the indictment of I. Lewis
"Scooter" Libby, Vice President Dick Cheney's chief of staff.

Reid demanded the Senate go into closed session. With a second by Sen. Dick Durbin, D-Ill., the public was ordered out of the chamber, the lights were dimmed, senators filed to their seats on the floor and the doors were closed. No vote is required in such circumstances.

Don't anyone ever tell me again that Senator Reid is dull.

Just noticed; Josh Marshall has the whole speech up at TPM Cafe; go read it.

If only it was raining so I could start singing and tap dancing. Oh, what the hell, I'm going to anyway.
