President Barack Obama and Republican challenger Mitt Romney are facing off for the second time Tuesday night, in the next-to-last debate before election day.
Obama will have to rally from a lackluster performance at the candidates' first showdown Oct. 3 in Denver, when an aggressive Romney outgunned both the president and moderator Jim Lehrer. But the Democrat may be boosted by his running mate Joe Biden's strong showing against Republican vice presidential nominee Paul Ryan on Thursday.
The presidential candidates are sparring over foreign and domestic policy at Hofstra University, in a 90-minute, town-hall style session, moderated by CNN's Candy Crowley. Their first debate focused on domestic affairs.
The major networks and cable news channels are broadcasting the debate -- which runs from 9-10:30 p.m. ET.
NPR is covering the event live on the radio.
Online, the debate is being streamed on Livestream, YouTube, Facebook Live and various news sites including the Politico Live and the Washington Post.
Here are the details for next week's final debate between Obama and Romney:
