Rush Limbaugh doubled down on his incendiary comments about Sandra Fluke, the Georgetown law student who was denied the right to speak at a contraception hearing, during his Friday show.

The conservative radio host sparked outrage on Wednesday when he called Fluke "a slut" and "a prostitute." He alleged that she was "having so much sex" that she couldn't afford contraception.

He went further the next day, adding, "if we're going to pay for your contraceptives and thus pay for you to have sex, we want something for it. We want you to post the videos online so we can all watch."

The controversy snowballed as pundits and political figures fiercely condemned Limbaugh's incendiary comments, and one advertiser withdrew its commercials from the radio program. President Obama even called Fluke on Friday to offer his support.

However, the fall-out in the wake of his comments did not stop Limbaugh from making more attacks about Fluke on Friday. "She was not allowed to testify because it was not about women at Georgetown who have so much sex they can't afford birth control," he thundered.

He said that her speech at a press conference served to show that "she's having so much sex she can't pay for it, and we should."

Fluke had testified about the reproductive and broader medical reasons for birth control, and cited the cost. Limbaugh said she was having "$3000 worth of birth control pills worth of sex."

He described her testimony from his perspective. "So the woman comes forth with this frankly hilarious claim that she's having so much sex -- and her buddies with her-- that she can't afford it," Limbaugh continued. "And not one person says, did you ever think about maybe backing off the amount of sex that you have?"

He said that his comment about a sex tape was merely him "illustrating absurdity by being absurd," imploring his critics to "lighten up."

Limbaugh also reacted to President Obama's call to Fluke. Obama told Fluke that her parents should be "proud" of her. Limbaugh had a different message for them. "I'd be embarrassed," he said. "I'd disconnect the phone. I'd go into hiding."
