John SununuJohn Sununu, Boston Globe columnist and former Republican New Hampshire Senator, promises no more commentaries about cable and Internet issues after watchdog Media Matters complained about an apparent conflict of interest.

The Time Warner Cable board member and paid honorary co-chair for the Broadband for America trade group penned criticism of the Obama Administration's "unnecessary regulation of the Internet."

Sununu, an "adjunct senior policy advisor" for lobbying firm Akin Gump Strauss Hauer & Feld, also rapped Uncle Sam's environmental oversight. Akin Gump has clients in the beleaguered coal sector.

Ellen Clegg, editorial page director of the Globe, said Sununu assured her he would no longer write about cable and Internet regulation. The paper views his role at Akin Gump as "very limited."

Clegg said the Globe would be more transparent, posting columnist bios online and linking them to their bylines.
