Federal judge taken off case for 'hostility' toward prosecution

The Chicago Sun-Times reports:

A federal appeals panel took the incredibly unusual step of pulling a federal judge off of a case in the middle of a trial because the judge showed unwarranted "anger and hostility'' toward prosecutors, the panel said Friday.

And it was not just any judge, but James Holderman, chief judge for the Northern District of Illinois.

Should Holderman be impeached?
