Jenner & Block partner and former federal prosecutor Reid Schar has been retained to serve as outside counsel to a New Jersey General Assembly committee investigating the role Gov. Chris Christie and his staff members played in creating a four-day traffic snarl by ordering the closing of lanes leading to the George Washington Bridge.

Schar, the cochair of Jenner’s white-collar defense and investigations practice, is well-versed in politically tinged scandals. As an assistant U.S. attorney in Chicago, he served as the lead prosecutor in both corruption trials involving former Illinois Gov. Rod Blogojevich, who was sentenced in 2011 to 14 years in prison.
