Who is moderating? CBS's Bob Schieffer will moderate for the third time. He moderated previously moderated debates in 2004 and 2008. 

What is the format? The final debate between President Obama and Mitt Romney will focus on foreign policy.  The topics, selected by Scheiffer, will cover:

  •  America’s role in the world
  • Our longest war — Afghanistan and Pakistan
  • Red lines — Israel and Iran
  • The changing Middle East and the new face of terrorism — I
  • The changing Middle East and the new face of terrorism — II
  • The rise of China and tomorrow’s world

The questions will be divided into six time segments of approximately 15 minutes each, and the candidates will be seated across a table from Schieffer. 

Where can I watch it? You can watch the debate on your computer or mobile device on The Washington Post Grid, which will be up around 4 p.m. ET. Most broadcast networks and cable news outlets are airing the debate in its entirety. 

How can I follow it on social media? The official Twitter hashtag is #debates, though some variations are also in use, including #lynndebate and #fpdebate. Tumblr will again live-GIF the debate in conjunction with the Guardian here. Each candidate has a page dedicated to the event — here is the Romney debate page and the Obama debate page.
