Advertisers keep deserting Rush Limbaugh as Obama weighs in

As Rush Limbaugh's radio show continues to lose advertisers, President Barack Obama Tuesda condemned the conservative talk show host's comments calling a Georgetown law student a "slut" for wanting health insurance to cover birth control.

"I don't know what's in Rush Limbaugh's heart, so I'm not going to comment on the sincerity of his apology," Obama said. "What I can comment on is the fact that all decent folks can agree that the remarks that were made don't have any place in the public discourse."

Limbaugh and his show have been under fire since last week, when he called Sandra Fluke a "slut" and a "prostitute" after she testified before Congress in support of a health-care rule that would require employers to give free contraception to women as part of their coverage.

The show has lost some two-dozen advertisers since the remarks, including high-profile names such as Netflix, Geico, Capitol One, AOL, Quicken Loans and others.

Limbaugh apologized last week and backed it up on Monday after some claimed the initial apology was insincere.

"Those two words were inappropriate, they were uncalled for, they distracted from the point that I was actually trying to make," Limbaugh said. "I again sincerely apologize to Miss Fluke for using those two words to describe her."
