Bill O'Reilly is one of the most polarizing commentators on American politics

He's been with right-leaning cable news outlet Fox News for 20 years and very much in the midst of this mental election campaign.

The funny thing with appearing on Stephen Colbert's show is that Colbert based his previous fictitious character (from The Colbert Report) on O'Reilly, so their conversations are always somewhat loaded. That said, they're also always a fascinating watch.

O'Reilly talks Donald Trump, Mike Pence and if the election is actually rigged.
