An amateur cameraman claims he's got video proof that California Sen. Barbara Boxer's supporters enlisted day laborers to hold signs protesting her Republican opponent. Derek Broes, a supporter of GOP Senate nominee Carly Fiorina, has released a video he shot outside a Pasadena debate that showed two Spanish-speaking men holding a slapdash white sign accusing "corporate cash" of loving the Republican candidate. Though the audio is hard to hear, one of the men clearly says he did not make the sign -- another appears to say a "lady" was paying them to hold it.
