California state Sen. Leland Yee, a Democrat from San Francisco, is leading a fight in demanding an apology from Limbaugh.

In recent days, the state lawmaker has rallied civil rights groups in a boycott of companies like Pro Flowers, Sleep Train and Domino’s Pizza that advertise on Limbaugh’s talk show.

During a Jan. 19 program, Limbaugh said there was no translation of President Hu Jintao’s speech during a visit to the White House. He launched into a 20-second-long imitation of the Chinese leader’s dialect.

Shortly after condemning Limbaugh’s remarks, Yee says he received racist death threats to his San Francisco and Sacramento offices.
