A U.S. congressman is riled up over plans to place ads promoting Islam on New York subway cars. The ads, which are slated to debut in September to coincide with Ramadan, feature key words or phrases about Islam (such as “Head Scarf?” or “Prophet Muhammad?”) and then the words “You deserve to know” along with WhyIslam.org.

Rep. Peter King, a New York Republican, says he doesn’t have a problem with the ad campaign itself, but he has a ”very, very real problem with those behind it.” While the main grass-roots organization sponsoring the campaign is the Islamic Circle of North America, one of the supporters is Siraj Wahhaj, an imam who was a character witness for convicted 1993 World Trade Center bombing mastermind Sheikh Omar Abdel-Rahman.

On Monday, New York Mayor Michael Bloomberg did not join in King’s outrage about the ads.

“If you were to advocate becoming a Muslim, I assume the First Amendment would protect you,” he said.

But King, noting that the ads would be up during the seventh anniversary of the September 11 attacks, said, “I’m calling on the MTA not to have these ads, not to go forward with them, and I don’t see this as a free speech issue at all.”
