Investigate the investigators

The LAT published today an article from the Associated Press reporting that some House members introduced a proposal that would direct the House Judiciary Committee to investigate whether to impeach Alberto Gonzales. It isn't clear how much support there is for this. It also isn't clear why it's necessary given that the Judiciary Committees of both houses have been investigating Gonzales for seven months. It helps Democrats, presumably, to start another investigation, since they can't legislate.
