PROVIDENCE, R.I. (AP) — A number of top Rhode Island politicians are boycotting a talk radio station because one of its hosts used a vulgarity to describe protesters in September.

The host called protesters parasites, cockroaches, "union hags" and "whores," spelling out the word.

He apologized last week, but a union-backed campaign to get him off the station has continued.

Those who have signed on as of Friday included some frequent guests on the station, including Republican gubernatorial candidate Ken Block. Also signing on are GOP Chairman Mark Smiley, as well as Democrats that include Gov. Lincoln Chafee, both U.S. senators and U.S. Rep. Jim Langevin.

The host's lawyer Tim Dodd said it's an attempt to suppress free speech. Dodd said he has been critical of unions, and of Chafee, and they now want to silence him.
