Robert Bell, co-head of Kaye Scholer’s antitrust practice in Washington, D.C., has joined Hughes Hubbard & Reed as a partner. Bell is the third practice leader to leave Kaye Scholer in recent weeks.

Since 2012, Bell has been handling one of the more lucrative cases in Kaye Scholer’s client portfolio, representing an unidentified Japanese auto parts manufacturer in an ongoing criminal antitrust investigation being conducted by the U.S. Department of Justice into dozens of international auto parts manufacturers.
