Former Deputy Attorney General Rod Rosenstein is joining King & Spalding in Washington, D.C., as an equity partner, marking the latest addition of former top Justice Department brass at the firm.

Rosenstein spent nearly two decades in senior positions at the Justice Department spanning the Bush, Obama and Trump administrations. But his time in the Trump administration overseeing special counsel Robert Mueller’s investigation makes him one of the most well-known DOJ lawyers and a prized recruit for any major law firm. He left the Justice Department last May and said in an interview Wednesday that he’s been job searching since September.
