Enough.

Think Progress:

"Dear Madam Secretary:

On March 12, 2007, I sent you a letter renewing, as formal requests of the Committee, prior letter requests that I sent to you between 2003 and 2006. These requests sought information on the claim that Iraq sought uranium from Niger, White House treatment of classified information, the appointment of Ambassador Jones as “special coordinator” for Iraq, and other subjects. My March 12 letter is attached.

The March 12 letter requested a response by March 23 to several of the inquiries, but the Committee received no response from you.

I now request your appearance before the Committee at a hearing on Wednesday, April 18, 2007, at 10:00 a.m. in Room 2154, Rayburn House Office Building. At this hearing, you will be asked to provide testimony and respond to questions on the subjects outlined in the March 12 letter and the original request letters. …

Sincerely,
Henry A. Waxman
Chairman"
