The non-profit group that provides life-saving medical screenings to millions of women every year is only used by "hookers," according to right-wing conspiracy host Glenn Beck.

He made the startling comment during his radio broadcast Monday, mocking MSNBC host Lawrence O'Donnell's impassioned defense of the Planned Parenthood Federation of America.

"Stop just a second!" Beck said as they played a recording of O'Donnell recounting a letter he'd received. "Hookers? Who depends on Planned Parenthood? I've got 400 abortions that I have to have! I have to have these children aborted!"

Beck recently announced that he'd be leaving the Fox News Channel later this year. His show has lost about a third of its audience in the last year, along with more than 300 advertisers who faced a sustained boycott by progressive activists. Beck did not say why he was leaving the network.

Independent research shows that each year Planned Parenthood plays a role in preventing over 2 million unwanted pregnancies and stopping over 800,000 women from getting abortions, saving public agencies billions of dollars in the process.

Without the group, research shows that America's overall abortion rate would be two-thirds higher, with numbers nearly doubling among poorer women. The group says that only three percent of their patients request abortion services.
