Trump's Attorney Tells Critic, 'F--- You,' And 'Back Off B----'

President Trump's personal attorney reportedly threatened and used profanity against a stranger who emailed him and asked him to resign Wednesday night.

ProPublica reports that Marc Kasowitz, who is representing the president on the Russia collusion investigation, responded in a profanity-laced tirade to an email from a citizen who wrote in the subject line: "Resign Now."

One of Kasowitz's responses read, "I'm on you now. You are f---ing with me now Let's see who you are Watch your back , b----," according to the report.

Another email taunted the man and demanded that he call Kasowitz, calling him "afraid" and a "piece of s---."

He also wrote, "I already know where you live, I'm on you," according to the report, which noted that Kasowitz even gave the man his personal cell phone number.

ProPublica later published an apology issued by Kasowitz's spokesman, which quoted Kasowitz as follows: "The person sending that email is entitled to his opinion and I should not have responded in that inappropriate manner. I intend to send him an email stating just that. This is one of those times where one wishes he could reverse the clock, but of course I can’t."

In the email, the man — who is not identified — wrote a short two-sentence message to Kasowitz in which he said that it was in "your interest and the long-term interest of your firm" to resign from advising the president. Five minutes later, Kasowitz responded: "F--- you" he wrote. Kasowitz continued writing messages, unprompted by any further replies from the man, and the replies got continually more abusive.

The news comes on the heels of a report that Kasowitz doesn't have security clearance and doesn't appear likely to get one due to struggles with alcohol, despite the fact that this could make defending his client difficult. The firm denied that he struggled with alcohol.

In addition, the New York Times reported that Kasowitz's relationship with the Trump White House was turning sour, and he could resign, another claim that the firm disputed.

Kasowitz is a trial lawyer and partner of the New York-based law firm Kasowitz Benson Torres. He founded the firm with his partners in 1993 and has been the personal outside attorney for Trump for a long time. Kasowitz was retained to represent Trump on the Russia investigation on May 24. He also reportedly represents clients with ties to Vladimir Putin.
