Carolyn Kubota, a former federal prosecutor and a partner at O'Melveny & Myers in Los Angeles since 2000, has joined Covington & Burling.

Covington's addition of Kubota, a white-collar litigation and defense expert, is the firm's latest new hire in Los Angeles, where the Washington, D.C.-based firm set up shop in early 2015.

A couple of close connections at Covington sold Kubota on the firm, she said. Two of its earliest hires in Los Angeles, partners Mitchell Kamin and Dan Shallman, once worked at O'Melveny & Myers with Kubota. Shallman, whose office was next to hers at their previous firm, also overlapped with Kubota during her 12-year stint at the U.S. attorney's office in Los Angeles, where she once served as deputy chief of the major frauds section.
