U.S District Judge Gerald Rosen's closed-door meeting at CIA headquarters with Justice Department officials and a witness whose testimony was key in the judge's decision to reverse convictions in a terrorism trial has raised the eyebrows of some legal experts. The meeting was held without the presence of defense lawyers because of concerns about protecting secret information under federal law. Some experts say Rosen's actions were highly unusual and could provide grounds for lawyers to challenge his impartiality in the case. "A judge is not supposed to engage in investigation off the record and with people who are aligned with one of the parties," said Peter Henning, professor in the WSU Law School.
