In 2006, shortly after securing guilty verdicts against both, Berkowitz left the Department of Justice to become a partner at Latham & Watkins LLP in Chicago.
Berkowitz was assigned to the Task Force in December 2003 from the U.S. Attorney's Office for the Northern District of Illinois, where he led many high-profile prosecutions of white collar crime and corporate fraud.
Berkowitz cross-examined Jeffrey K. Skilling (Enron President and COO), sending the former CEO into a temper tantrum on the stand.
He was also the ending voice for the prosecution as he concluded the government’s closing arguments to the jury by urging them to send a message to Lay and Skilling that "you can’t buy justice, you have to earn it."
Berkowitz married Bethany McLean, a Vanity Fair magazine editor and one of the authors of the book Enron: The Smartest Guys in the Room, in May 2008.
