After four years at the U.S. Department of Justice leading the charge against Foreign Corrupt Practices Act violators, Charles Duross soon will offer his help to Morrison & Foerster clients looking to keep the DOJ’s FCPA investigators at bay.

Duross on Friday stepped down as the head of DOJ’s FCPA Unit to join Morrison & Foerster on Feb. 17 as a partner in the firm’s Washington, D.C., office, the firm announced Monday. He will lead Morrison & Foerster’s anticorruption practice.
