Trump's consiglieri

Marc Kasowitz, President Trump’s personal attorney on the Russia case, threatened a stranger in a string of profanity-laden emails Wednesday night.

The man, a retired public relations professional in the western United States who asked not to be identified, read ProPublica’s story this week on Kasowitz and sent the lawyer an email with the subject line: “Resign Now.’’

Kasowitz replied with series of angry messages sent between 9:30 p.m. and 10 p.m. Eastern time. One read: “I’m on you now. You are fucking with me now Let’s see who you are Watch your back , bitch.”

In another email, Kasowitz wrote: “Call me. Don’t be afraid, you piece of shit. Stand up. If you don’t call, you’re just afraid.” And later: “I already know where you live, I’m on you. You might as well call me. You will see me. I promise. Bro.”

Kasowitz’s spokesman, Michael Sitrick, said Thursday he couldn’t immediately reach Kasowitz for comment.

ProPublica confirmed the man’s phone number matched his stated identity. Technical details in the emails, such as IP addresses and names of intermediate mail servers, also show the emails came from Kasowitz’s firm. In one email, Kasowitz gave the man a cell phone number that is not widely available. We confirmed Kasowitz uses that number.

The exchange began after the man saw our story featured last night on the Rachel Maddow show on MSNBC. We reported that Kasowitz is not seeking a security clearance even though the Russia case involves a significant amount of classified material.

Experts said Kasowitz could have trouble getting a security clearance because of what multiple sources described as a recent history of alcohol abuse. Former employees also said Kasowitz had engaged in behavior that made them uncomfortable.

Since the story was published, his spokesman issued a statement disputing several parts of the story: “Marc Kasowitz has not struggled with alcoholism,” Sitrick wrote. “He has not come into the office intoxicated, attorneys have not had to go across the street to the restaurant during the workday to consult Kasowitz on work matters.”

The rigorous background investigation that goes into getting security clearance also considers “any information relevant to strength of character, honesty, discretion, sound judgment, [and] reliability.”

The exchange of emails Wednesday began at 9:28 p.m. Eastern when the man sent the following message to Kasowitz’s firm account.

Five minutes later, Kasowitz responded with two words:

Fifteen minutes after that, Kasowitz sent a second email:

The man responded politely:

But Kasowitz continued to harangue him:

And then, just 33 minutes after the man’s initial email, Kasowitz sent a fourth response, referring to his own Jewish heritage and the man’s name, which he presumed to be Jewish.

The man told us that the email exchange disturbed him so greatly he forwarded it to the FBI so there would be a written record in case Kasowitz followed through on the threat.
