WASHINGTON — Facebook Inc. has signed on with a former U.S. Federal Communications Commission chairman and other Patton Boggs lobbyists.

Patton Boggs disclosed to Congress on Tuesday that partner Kevin Martin, the FCC chairman from 2005 to 2009, as well as partner Jeffrey Turner and senior public policy adviser Emanuel Rossman, are lobbying for the social network. They are focusing on matters concerning “technology and Internet policy, including personal privacy, protecting children, advancing online security, and tax policy issues,” according to a lobbying registration report the law firm filed with the U.S. House of Representatives.
