Amanda Kramer, a longtime assistant U.S. attorney in Manhattan who has prosecuted a range of high-profile fraud and sex-crime defendants, including Anthony Weiner, has joined Covington & Burling in New York as a partner.

Kramer’s return to private practice—she’d previously been an associate at Weil, Gotshal & Manges—comes after about 11 years in the Southern District on New York U.S. Attorney’s office, where she prosecuted human trafficking, financial crimes such as health care and mortgage fraud and other serious offenses. She was most recently a senior member of the Securities and Commodities Fraud Task Force.
