Donald Trump speaks to a crowd.

Donald Trump on Friday continued to defend himself against a mounting number of sexual assault allegations by seemingly mocking the appearance of some of his accusers, suggesting they are making the claims for fame, and warning that anyone could be accused of sexual assault - even President Obama.

"Some are doing it for, probably, a little fame," Trump said during his rally here. The Republican nominee wondered aloud about the timing of the accusations - less than 30 days before the election - and called the accusations "phony," "totally invented, fiction, 100 percent totally and completely fabricated."
