4:00 PM -- The President calls the raid a "total witch hunt" and an "attack on what we all stand for."
President Trump's attorney was raided by the FBI Monday ... and the operation was put in motion by none other than Special Counsel Robert Mueller.
We've confirmed federal agents swooped into Michael Cohen's NYC office with a search warrant, and seized thousands of documents related to Mueller's Russia investigation. They also reportedly grabbed records of Cohen's $130,000 payment to Stormy Daniels.
Cohen's attorney says the U.S. Attorney's Office for the Southern District of New York got the search warrant based on a referral from Mueller.
The seized docs include communications between Cohen and President Trump ... according to the NY Times, which first reported the raid.
Cohen's attorney called the raid heavy-handed because "It resulted in the unnecessary seizure of protected attorney client communications between a lawyer and his clients." He added, Cohen's been fully cooperative with Congress throughout the investigation, and has sat for depositions under oath.
