A federal judge is poised to hear arguments this week in a joint motion by former FBI Director James Comey and New York Attorney General Letitia James seeking to disqualify interim U.S. Attorney Lindsey Halligan from overseeing their criminal prosecutions in the Eastern District of Virginia.

U.S. District Judge Cameron McGowan Currie, an appointee of former President Bill Clinton sitting by designation from South Carolina to avoid conflicts in the district, will preside over the hearing Thursday morning. Currie has already ordered full grand jury transcripts for review, signaling an unusual level of scrutiny of what Halligan’s role was before the indictments were handed up to her by grand jurors.
