Randi Rhodes, an afternoon host for the progressive Air America radio network, was suspended Thursday after repeatedly insulting Senator Hillary Rodham Clinton at an event last month.

Ms. Rhodes used vulgar language that likened Mrs. Clinton to a prostitute at an event sponsored by KKGN, the Air America affiliate in the San Francisco area, on March 22. A video of Ms. Rhodes remarks was published to the video-sharing Web site YouTube on Tuesday, prompting condemnations by some bloggers.

In a statement, Charlie Kireker, the chair of Air America, said the radio network encourages strong opinions about public affairs but does not condone such abusive, ad hominem language by our hosts.

The network called Ms. Rhodes suspension indefinite and did not elaborate on the fate of her daily three-hour radio show. The Randi Rhodes Show is normally broadcast from 3 to 6 p.m. weekdays. Sam Seder, another Air America host, was scheduled to fill in for Ms. Rhodes on Thursday.

On the video, Ms. Rhodes is also shown using derogatory language to describe Geraldine A. Ferraro, a former congresswoman and a supporter of Mrs. Clinton. Ms. Ferraro resigned from a committee of Mrs. Clintons campaign last month after making controversial remarks about Senator Barack Obama.

Earlier this year, David Shuster, a reporter for MSNBC, was been suspended because of comments he made about Chelsea Clinton. Mr. Shuster said Ms. Clinton had been pimped out to make calls to superdelegates on behalf of her mother.
