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.
