The final presidential debate is 9 p.m. today at the University of Nevada-Las Vegas, where Democratic nominee Hillary Clinton and Republican nominee Donald Trump will face off.
The third debate will be divided into six time segments of about 15 minutes each on topics selected by moderator Chris Wallace of Fox News and announced by the Commission on Presidential Debates.
Topics will be debt and entitlements, immigration, economy, Supreme Court, foreign hot spots and fitness to be president.
The moderator will open each segment with a question, after which each candidate will have two minutes to respond. Candidates will then have an opportunity to respond to each other. The moderator will use the balance of the time in the segment for a deeper discussion of the topic.
The nationally televised debate will be broadcast on most major networks and leading cable news networks and is scheduled to last 90 minutes.
