The attorney who represented a controversial Republican member of Congress in a number of defamation lawsuits now faces a legal roadblock uncommon for pro hac vice admissions in the District of Delaware.

Virginia attorney Steven Biss’ ability to practice in the Delaware court has been questioned by Rhode Island attorney Michael Farley, a pro se defendant in a case filed last year by a man seeking $25 million in damages for alleged defamation, false light invasion of privacy and civil conspiracy. Farley made the allegations in an opposition to a motion to admit Biss and a motion to disqualify.
