BOSTON — Republican presidential contender Mitt Romney, who rails against the "cesspool" of pornography, is being criticized by social conservatives who argue that he should have tried to halt hard-core hotel movie offerings during his near-decade on the Marriott board.

Two anti-pornography crusaders, as well as two conservative activists of the type Romney is courting, say the distribution of such graphic adult movies runs counter to the family image cultivated by Romney, the Marriotts and their shared LDS faith.

"Marriott is a major pornographer. And even though he may have fought it, everyone on that board is a hypocrite for presenting themselves as family values when their hotels offer 70 different types of hard-core pornography," said Phil Burress, president of Citizens for Community Values, an anti-pornography group based in Ohio.

Tony Perkins, president of the Family Research Council, a leading conservative group in Washington, said, "They have to assume some responsibility. It's their hotels, it's their television sets."

During a recent Associated Press interview, Romney said he did not recall pornography coming up for discussion while he was on the Marriott board from 1992 to 2001. Despite being chairman of the board's audit committee, he also said he was unaware of how much revenue pornography may have generated for the hotel chain.

Romney said his current concern is not about pornography per se, but children unwittingly stumbling upon it on the Internet or television.

"I am not pursuing an effort to try and stop adults from being able to acquire or see things that I find objectionable; that's their right. But I do vehemently oppose practices or business procedures that will allow kids to be exposed to obscenity," the former Massachusetts governor said.

Pornography is a lucrative business for various hotel chains. Estimates vary widely, up to $500 million annually industrywide by one opponent, John Harmer, who served as California's lieutenant governor under Ronald Reagan.

Marriott and other major hoteliers say they offer pay-per-view pornography because their customers demand it and entertainment service contracts require it to underwrite first-run movies and free television.

"It certainly would have been wrong to impose his own personal beliefs if they were contrary to the financial interests of the company," Marriott spokesman Roger Conner said of Romney.

Marriott had a contract with On Command Corp. for its television and movie services during Romney's board tenure. Conner said the contract was signed in 1991 — the year before Romney joined the board. He served until 2001 and was paid $25,000 annually, plus stock.
