How long will the first presidential debate last? Monday's schedule for Clinton vs. Trump

The presidential election is about to heat up when Donald Trump and Hillary Clinton meet face to face Monday in the first of three televised debates. All three debates will take place from 9 p.m. to 10:30 p.m. Eastern without commercial interruption, bringing each debate to about an hour and a half.

The first debate is set for Monday, Sept. 26 at Hofstra University in New York. NBC News' Lester Holt will moderate.

The highly anticipated debate will be divided into six segments of 15 minutes each. The topics were selected by Holt and were announced about a week before the debate — America's direction, achieving prosperity and securing America. Each candidate will have two minutes to respond to each question, then have a chance to respond to each other.
