Oh noes! World Net Daily is outraged and seething! CBS Outdoor is stifling their First Amendment rights by refusing to sell them billboard space to promote the dreaded nirth certifikit conspiracy: Cover-up: CBS bans eligibility billboards.

WASHINGTON – The company touting itself as the “world’s largest out-of-home media” enterprise has banned WND’s national billboard campaign that asks one simple question: “Where’s the birth certificate?”

CBS Outdoor, a division of CBS Corp. that sells more outdoor advertising than any other billboard company in North America, refuses to accept purchases of space on any of its 550,000 displays nationwide, media buyers for WND report.

The billboard campaign was begun last month by Joseph Farah, editor and chief executive officer of WND, due to his frustration with media colleagues not giving attention to what he sees as critical questions about Barack Obama’s constitutional eligibility to serve as president.

“Here we have one of the largest media companies in the U.S. now not only refusing to allow news coverage of a vitally important national question being asked by millions of Americans, but one that won’t even permit the purchase of space to raise the question,” said Farah. “What is the value of a First Amendment in a country when this kind of self-censorship is at work – self-censorship specifically geared to stifle inquiry and debate about the most powerful person in the country.”
