Current FBI leadership is investigating allegations that the agency conducted an unauthorized operation to infiltrate Donald Trump’s 2016 presidential campaign using two female undercover agents, according to a Tuesday report. The operation, reportedly ordered by then-FBI Director James Comey in 2015, was disclosed by a whistleblower to the House Judiciary Committee and first reported by The Washington Times in October.

The whistleblower claims Comey personally directed the off-the-books investigation targeting Trump shortly after he announced his candidacy. Two female agents were allegedly tasked with acting as “honeypots” to gather information, traveling with Trump and his team.

The operation is said to have lacked proper justification and was not documented in FBI systems, potentially concealing it from the Justice Department Inspector General. The FBI has not yet commented on the allegations, which, if proven true, could suggest institutional bias against Trump during his campaign.
