MIAMI (AP) - A conservative radio talk show host tapped to be chief of staff for incoming U.S. Rep. Allen West is stepping down from her congressional job a day after 300 Florida schools were locked down when a threat was linked to her show.

Joyce Kaufman announced Thursday that she would not be West's aide. Kaufman said on her show that she wants to avoid any repercussions to the Florida Republican, but she didn't elaborate and hasn't returned telephone messages.

Kaufman has drawn fire for some of comments. At a recent tea party rally, she told the crowd that if "ballots don't work, bullets will."

Police have said the e-mail mentioned gun rights but they have refused to release its contents.
