Samuel Feder, the general counsel of the Federal Communications Commission, is leaving his post of about three years to become a partner at law firm Jenner & Block. Feder, who has worked closely with Chairman Kevin Martin since coming to the FCC in 2001, will be replaced by Matthew Berry, according to release by the agency. Feder worked with Martin on radio spectrum and international policy issues.

"Sam provided exceptional legal advice on every matter we faced and also played a crucial role in policy development. I have worked with Sam since the day I became a Commissioner in 2001, and I will greatly miss his excellent judgment and wise counsel," Martin said in a release.
