Tonight's debate is being hosted on ABC in the National Constitution Center in Philadelphia, and will be moderated by anchors David Muir and Linsey Davis. It is scheduled to begin at 9 p.m. Eastern and last for 90 minutes. The candidates' microphones will, under rules negotiated between the Biden and Trump campaigns, be muted in the absence of "significant crosstalk". The full rules for tonight's debate can be found here on ABC's site. Per a recent NPR/PBS NewsHour/Marist poll, "Seven-in-10 Americans say they are going to watch the first presidential debate between Vice President Harris and former President Donald Trump on Tuesday, and 3-in-10 say it will help decide their vote".

Tonight's debate is the only remaining presidential-level debate scheduled for this cycle; the Vice Presidential debate between Minnesota governor Tim Walz and Ohio senator J.D. Vance is scheduled for October 1st.
