WASHINGTON DC: The Republican-appointed chairman of US media regulator, the Federal Communications Commission, has come under fire from members of his own party for his proposals to tighten controls on cable TV providers.

Republican congressmen are to deliver a letter to Kevin J Martin condemning his plans as "misguided and harmful" and "inappropriate at best".

Martin claims the cable industry has grown sufficiently to trigger new restrictions, but opponents of the move question the accuracy of his numbers and want more information on the planned rules.

Martin is also under attack over proposals to relax cross-media ownership rules, amid concern that such moves would diminish choice for consumers.
