Editor's update: 6:00 PM EDT - According to a knowledgeable Congressional source, "there is a chance that Dr. Griffin's confirmation by the full Senate may happen tonight. It may be done by unanimous consent, without a committee vote."
Vote on NASA nominee delayed, Daily Press
"A Senate committee delayed a vote on President Bush's nominee to head NASA on Tuesday, after Sen. George Allen of Virginia complained that rocket scientist Michael Griffin didn't adequately explain his position on aeronautics research."
Editor's note: Congressional sources note that Sen. Frist has expresed interest in holding the Senate in session on Thursday to vote on Griffin's nomination. Formal swearing in for Griffin would be held on Monday morning, followed by an all-hands address to the agency. Those plans may now be slightly delayed due to Sen. Allen's actions.
Editor's update: Congressional sources tell NASA Watch that Allen's concerns about aeronautics have been satisfied and that Allen has released the hold he had placed on Griffin's nomination.
Editor's update: I just got a note (2:20 pm EST) originating from the Senate Commerce Committee: "Senate Commerce Committee Co-Chairmen Ted Stevens and Daniel Inouye have added the nomination of Dr. Michael Griffin to be the NASA administrator to the Committee's previously scheduled mark-up at 10am on Thursday, April 14 in room 253 of the Russell Building."
