Several Am Law 200 law firms this week added federal prosecutors to their white-collar defense and investigation practices, amid a string of lateral moves from the government lately into Big Law. Lawyers who just left the U.S. Attorney’s offices landed at Covington & Burling in New York, Thompson Hine in D.C. and Boies Schiller Flexner in Los Angeles, according to firm announcements this week.

Some of the new hires said they anticipate the government to pursue cases in national security matters, artificial intelligence, anti-corruption and financial fraud in the coming months.
