Hamilton and Kerrey bailed out partway through
From Reuters:
Two Democrats on the panel, Vice Chairman Lee Hamilton and former U.S. Sen. Bob Kerrey of Nebraska, left the session about an hour early. Hamilton, a former congressman from Indiana, was said to have had a prior commitment to introduce visiting Canadian Prime Minister Paul Martin at a lunch.
Saw a lot of this kind of thing during the hearings. The committee member would make his long, political speech, ask a few questions, and then leave. It was obvious that to some members the function of this committee was something other than hearing what the witnesses had to say.
David Kay wound up his presentation with about half the committee members gone.
