Live coverage of the second presidential debate between Republican Donald Trump and Democrat Hillary Clinton from Washington University in St.Louis, Missouri.

The debate will take the form of a town meeting, with half the questions being posed directly by citizen participants and the other being posed by the moderator based on topics of broad public interest as reflected in social media and other sources.

The candidates will have two minutes to respond and there will be an additional minute for the moderator to oversee more discussion. The town meeting participants will be uncommitted voters selected by the Gallup Organization.
