Vice President Kamala Harris and former President Donald Trump Tuesday night will face off in their first presidential debate. And while its the second debate of the general election, its the first between the two candidates -- and the first time Harris and Trump will meet in person.
When they do, they'll both be asked adhere to a set of rules the candidates agreed upon last week.
As the debate gets underway, here's a look at what to expect.

List of debate rules
The parameters now in place for the Sept. 10 debate are essentially the same as they were for the June debate between Trump and President Joe Biden.

According to ABC News, the candidates will stand behind lecterns, will not make opening statements and will not be allowed to bring notes during the 90-minute debate. David Muir and Linsey Davis will moderate the event.
“Moderators will seek to enforce timing agreements and ensure a civilized discussion,” the network noted.
A Harris campaign official, who spoke on the condition of anonymity to discuss planning around the debate, said a candidate who repeatedly interrupts will receive a warning from a moderator, and both candidates' microphones may be unmuted if there is significant crosstalk so the audience can understand what's happening.
After a virtual coin flip held Tuesday and won by Trump, the GOP nominee opted to offer the final closing statement, while Harris chose the podium on the right side of viewers’ screens. There will be no audience, written notes or any topics or questions shared with campaigns or candidates in advance, the network said.
Here's the full list of rules:
- The debate will be 90 minutes with two commercial breaks.
- The two seated moderators, David Muir and Linsey Davis, will be the only people asking questions.
- A coin flip was held virtually on Tuesday, Sept. 3, to determine podium placement and order of closing statements; former President Donald Trump won the coin toss and chose to select the order of statements. The former president will offer the last closing statement, and Vice President Harris selected the right podium position on screen (stage left).
- Candidates will be introduced by the moderators.
- The candidates enter upon introduction from opposite sides of the stage; the incumbent party will be introduced first.
- No opening statements; closing statements will be two minutes per candidate.
- Candidates will stand behind podiums for the duration of the debate.
- Props or prewritten notes are not allowed onstage.
- No topics or questions will be shared in advance with campaigns or candidates.
- Candidates will be given a pen, a pad of paper and a bottle of water.
- Candidates will have two-minute answers to questions, two-minute rebuttals, and one extra minute for follow-ups, clarifications, or responses.
- Candidates' microphones will be live only for the candidate whose turn it is to speak and muted when the time belongs to another candidate.
- Candidates will not be permitted to ask questions of each other.
- Campaign staff may not interact with candidates during commercial breaks.
- Moderators will seek to enforce timing agreements and ensure a civilized discussion.
- There will be no audience in the room.
Trump reluctantly agreed to the mute function when he faced Biden in June, but after that debate, his team determined it was a net positive if voters did not hear from the Republican former president while his opponent was speaking. Harris’ team was pushing to return to a normal format without mute buttons.
Are other debates planned?
Though the September debate is currently the only debate currently planned between Harris and Trump, Harris' campaign said that a potential October debate was contingent on Trump attending the Sept. 10 debate.
In addition to the planned Harris-Trump debate on Sept. 10, vice presidential candidates Tim Walz and JD Vance also agreed to a debate, scheduled to be hosted by CBS News on Oct. 1.
When is Election Day?
Voters will officially head to the polls just over a month later on Nov. 5 for Election Day, though early voting starts significantly earlier in many states.
In Illinois, early voting will begin on Sept. 26 and will run through Nov. 4, with Election Day voting held at a designated polling place from 6 a.m. to 7 p.m. on Nov. 5.
