SEATTLE (AP) — Seattle U.S. Attorney Brian Moran, the top federal prosecutor for western Washington, has announced his last day in office will be Feb. 28. President Joe Biden has asked U.S. attorneys appointed by former President Trump to step down. Moran, who previously served as one of the top officials in the state Attorney General’s Office, will return to private practice. In a statement Tuesday, Moran thanked Democratic U.S. Sens. Patty Murray and Maria Cantwell for supporting his nomination, and U.S. District Judge Ricardo Martinez thanked Moran for continuing the district’s tradition of having professional, nonpartisan prosecutors as U.S. attorneys.
