Some sleazily sourced stories are trying to convey the impression that Barack Obama attended a Muslim madrassa as a boy. It seems to be without factual foundation and the motives of those spreading the rumor are suspect, to put it mildly. Fox News' resident bigot, John Gibson, does not disappoint. But Obama's staff really need to do a better job of responding. Here's a not-for-prime-time soundbite:

"The allegations are completely false," says Obama spokesman Robert Gibbs. "To publish this sort of trash without any documentation is surprising, but for Fox to repeat something so false, not once, but many times is appallingly irresponsible. This is exactly the type of slash-and-burn politics the American people are sick and tired of."

It's "trash" to say that someone was raised a Muslim? Gibbs didn't mean that, did he?
