The U.S. Justice Department has launched a search for a new leader of the criminal division team tasked with handling some of the most significant white-collar prosecutions, including financial fraud and foreign bribery cases, according to a new job posting.

The announcement follows the departure of Andrew Weissmann, the last fraud division chief to hold the position on a permanent basis, who left the Justice Department to join the New York University School of Law. In 2017, Weissmann joined the special counsel, Robert Mueller III, in his investigation of the Trump campaign and Russia’s interference in the 2016 election.
