The third and final presidential debate of the 2016 election will take place at 8 p.m. today.

The University of Nevada-Las Vegas will host, and Fox News Sunday anchor Chris Wallace will moderate, the first Fox journalist to do so. Wallace, in conjunction with Bret Baier and Megyn Kelly, previously moderated Fox News Channel’s GOP primary debates. He is known for being a demanding interviewer of both Democrats and Republicans.

The debate format will follow the first presidential debate in which the hour and a half program is divided into six 15-minute segments. Each candidate will have two minutes to respond to the moderator’s question and then they can respond to what the other said. The topics were chosen by Wallace and announced a week in advance. The last showdown between Republican nominee Donald Trump and Democrat challenger Hillary Clinton will focus on debt and entitlements, immigration, the economy, the Supreme Court, foreign hot spots, and their respective fitness to be president.

Trump will have to answer to the sexual-assault allegations made against him in the wake of the Trump tape scandal as well as his claims that the media and Clinton-backers are rigging the election.

Meanwhile, Clinton will be expected to address for the most recent batch of internal emails, hacked from campaign head John Podesta, released by WikiLeaks since the last debate in St. Louis.

The first debate had a record-breaking viewership of 84 million and the second debate dropped down to 65.5 million viewers. C-SPAN and all major networks will broadcast as well as live-stream the debate.
