The Federal Bureau of Investigation is quickly becoming a farm system for King & Spalding, and vice versa.

On Monday, the firm said it added the FBI's Sumon Dantiki to its ranks as a partner in its special matters and government investigations group. Dantiki was most recently senior counsel at the agency, and his arrival follows closely on the heels of Zack Harmon, former FBI chief of staff, who announced his return to the firm last week.

"We have a long and proud history of our lawyers serving the public interest, including current FBI director Chris Wray and his former chief of staff, Zack Harmon, who worked closely with Sumon at the FBI," said Mark Jensen, managing partner of King & Spalding's D.C. office, in a statement. "Sumon's national security credentials are impeccable, and along with Zack's deep expertise, as a pair they offer companies, financial firms and research laboratories extraordinary insight into how to protect their data and technologies from global cybersecurity threats."
