Andrew A. Weissmann[3] (born March 17, 1958) is an American attorney and professor. He was an Assistant United States Attorney from 1991 to 2002, when he prosecuted high-profile organized crime cases.[4] He served as a lead prosecutor in Robert S. Mueller's Special Counsel's Office (2017–2019), as Chief of the Fraud Section in the Department of Justice (2015–2017) and is currently a professor at NYU Law School.[5]
Starting in 2015, he became the chief of the Criminal Fraud Section of the U.S. Department of Justice. In June 2017, he was appointed to a management role on the 2017 special counsel team headed by Robert Mueller. To assume that position, Weissmann took a leave from his Department of Justice post. The special counsel's investigation concluded in 2019 and Weissmann went into the private sector.
From 2002 to 2005, Weissmann was the deputy director appointed by George W. Bush, prior to his assignment as the director of the task force investigating the Enron scandal.[9] His work resulted in the prosecution of more than 30 people for crimes including perjury, fraud, and obstruction, including three of Enron's top executives, Andrew Fastow, Kenneth Lay, and Jeffrey Skilling. In a follow-up case in U.S. District Court, Weissmann also was successful, controversially, at arguing that auditing firm Arthur Andersen LLP had covered up for Enron. In that case, which resulted in the destruction of Andersen, he convinced the district judge to instruct the jury that they could convict the firm regardless of whether its employees knew they were violating the law.[4] That ruling was later unanimously overturned by the Supreme Court in Arthur Andersen LLP v. United States, in which the court held that "the jury instructions failed to convey the requisite consciousness of wrongdoing."[10][11]
In 2005, he worked as special counsel again with Mueller, before heading into private practice at Jenner & Block in New York after the special counsel completed its mandate. In 2011, he returned to the FBI, serving as General Counsel under Mueller.[12] From 2015 to 2017, he headed the criminal fraud section at the Department of Justice. Weissmann has taught at NYU School of Law, Fordham Law School, and Brooklyn Law School.[7]
On June 19, 2017, Weissmann joined Special Counsel Mueller's team to investigate Russian interference in the 2016 United States elections.[13][14][8] He was called "the architect of the case against former Trump campaign chairman Paul Manafort". A news report in March 2019 said he would soon leave the Justice Department and become a faculty member at New York University and work on public service projects.[15] In 2020, Weissmann returned to Jenner & Block as co-chair of its investigations, compliance and defense practice.[16]
Weissmann has been described as a "pitbull" by The New York Times, and critics have said he deployed "hard-nosed tactics and a 'win-at-all-costs' mentality" in the Enron prosecution.[15]
Media and publishing career
In 2019, Weissmann joined MSNBC as a legal analyst.[1] Since March 2023, he has co-hosted the MSNBC podcast Prosecuting Donald Trump (with fellow former prosecutor, Mary McCord), which won the 'Webby Winner' and 'People's Voice Winner' in the Crime & Justice category of the 2024 Webby Awards.[17][18]
