Republican primary hopeful Herman Cain appeared on 'Jimmy Kimmel Live' last night and calmly disputed sexual harassment claims by Chicago native Sharon Bialek. And like his recent campaign ad, the interview was filled with awkward moments.

During a TV press conference yesterday, Bialek claimed that Cain got hands-y with her in the back of a car in the 1990s. Bialek is the fourth woman to accuse the pizza-mogul-turned-presidential-candidate of inappropriate conduct.

Cain told Jimmy Kimmel there's "not an ounce of truth" to any of these accusations and he vowed to hold a press conference today to "set the record straight."

What do you think? Are there any truth to these claims? Or is Cain simply being targeted as a notable politician? Watch Cain's full interview below.
