Marc Kasowitz

According to a May 23, 2017 article in Forward, Kasowitz, Benson, Torres, and Friedman has been a "go-to source" for Donald Trump for decades. He has represented Donald Trump in his divorce proceedings, bankruptcy cases, Trump University lawsuits, during the 2016 presidential campaign regarding sexual misconduct allegations, and during the Trump presidency in the investigation of Russian interference in the 2016 United States elections.

In Spring 2017, Kasowitz told associates that he had been personally responsible for the abrupt dismissal of U.S. Attorney Preet Bharara on March 11, 2017, having previously warned Trump, "This guy is going to get you".

Kasowitz departed Trump's White House legal team on July 20, 2017.

In 2017, ProPublica reported that Kasowitz may be ineligible for a federal security clearance due to his alcohol abuse. After reading the articles, a currently unidentified individual sent an email to Kasowtiz urging him to "resign now." Kasowitz replied with a series of profanity-laced emails, some of which took a threatening tone, writing, "I'm on you now. You are fucking with me now Let's see who you are Watch your back, bitch," as well as "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."

According to U.S. court records, Kasowitz's clients include the Russian oligarch Oleg Deripaska, a close associate of Vladimir Putin and a business partner of Trump's former campaign manager Paul Manafort. Kasowitz also represents the Russian state-owned bank Sberbank, a bank under sanctions by the EU and the United States after Russia's 2014 annexation of Ukraine's Crimea region.

Kasowitz is married to Lori Kasowitz, whom he met while she was working as a manager at Mayer Brown. In 2001, they created the Marc E. and Lori A. Kasowitz Scholarship at Cornell Law School. In 2007, they pledged an additional $250,000 to the law school's endowment. He and his twin brother, Stephen, also established a scholarship at Hopkins Grammar School, which they attended growing up.

Kasowitz worked for the law firm Mayer Brown until 1993, when Kasowitz, 18 other lawyers, and two clients left Mayer Brown to establish the Kasowitz Benson Torres law firm.

After the 1993 World Trade Center bombing, Kasowitz defended the Port Authority of New York and New Jersey in a lawsuit filed by victims of the attack. In 2005, the Port Authority was ruled to be negligent. He has also defended Bill O'Reilly from allegations of sexual harassment, who was ultimately forced out at Fox News in April 2017.
