The debate will air on the leading major cable and television networks as well as C-SPAN.

How can I watch the debate online?

The websites for the major networks will also stream the debate live, as will C-SPAN's site.

Who will moderate the debate?

Chris Wallace, the anchor of Fox News Sunday, will moderate the final debate. Wallace is a three-time Emmy Award winning anchor for Fox News Sunday. He's worked for Fox News Channel since 2003 and previously spent 14 years working for ABC News. Wallace has covered almost every major political event for Fox. He's known for his aggressive questioning style of both Democrats and Republicans. In 2016, Wallace conducted an exclusive interview with President Barack Obama, the first one the president did on the channel since 2014. Wallace did previous interviews with Obama in 2008, 2009, and 2013.

He also had a famously testy 2006 interview with Bill Clinton in which he questioned whether the president did enough during his time in office to capture Osama Bin Laden.

What is the format of the debate?

The debate is split into six 15-minute segments covering topics picked by Wallace. Both Clinton and Trump will have two minutes to respond to a question and then another chance to respond to their opponent. Wallace will use the leftover times to expand on the discussion topic.

The six discussion topics will be immigration, entitlements and debt, the Supreme Court, the economy, foreign policy, and each candidate's fitness to serve as president.

How will the viewership for this debate compare to previous debates?

It's rare for viewership of the last presidential debate to surpass prior debates. In 2012 41 million people tuned into the third debate between Obama and Mitt Romney, according to Nielsen Ratings. By comparison 45 million people watched the second debate and just over 46 million watched the first one. In 2008 56 million people watched the third debate between Obama and Sen. John McCain, down from the 63 million but up from the first debate between the two candidates, which garnered 52 million people.

The trend in 2016 matches 2012 so far. The last debate between Clinton and Trump had a viewership of 66.5 million people, down from the record-breaking 84 million viewers who watched the first debate between the two presidential candidates.
