Sen. Scott Brown (R-Mass.) lashed out at comedienne Kathy Griffin on Thursday for describing his daughters as "prostitutes."

Brown strongly condemned remarks Griffin made on CNN in which she mocks Brown's daughters, Ayla and Arianna.

“People can call me any name they want, but families are off limits," Brown said. "I love my daughters Ayla and Arianna very much, and any parent would be proud to have them as children. Kathy Griffin and Bravo ought to be ashamed of themselves.”

Griffin is shown in video identifying a photo of Brown, in which she makes a joke about the Brown daughters.

"Scott Brown, who is a senator from Massachusetts, and has two daughters who are prostitutes," she tells CNN anchors John King and Dana Bash.

Brown has drawn some guffaws for his signs of affection toward his daughters; after winning a special election in January to fill the Senate seat of the late Sen. Edward Kennedy (D-Mass.), joking that the two were "both available."

Ayla Brown, a former college basketball player and "American Idol" contestant, works as contributor to "The Early Show" on CBS. Arianna Brown has spent this past summer doing some modeling.
