But he did not kick her off the Armed Services committee. He wasn't even able to kick her off of HIS committee. Just read the story you yourself posted.
Barton took the only action left to him after his retalitory request was turned down by leadership. His refusal to grant the waiver forces Wilson off Armed Services and has the same effect he was trying to achieve in the first place. Which means he didn't get the message when leadership turned down his request. IMO he's one skating on thin ice politically, but time will tell.
It is stupid because Wilson represents a merginal seat (it went for Kerry), and she needs all the help she can get. Barton retaliating over Wilson's interest as to what the perscription drug bill cost is not a pretty sight.
