Civil rights advocate Debo Adegbile is joining Wilmer Cutler Pickering Hale and Dorr as a litigator in the New York office, the firm said Monday.

Adegbile argued two voting rights cases before the U.S. Supreme Court for the NAACP Legal Defense and Educational Fund, where he was acting president and director-counsel after the death of John Payton, a former Wilmer partner. Adegbile served more recently as a senior counsel to the Senate Judiciary Committee.
