The debate could be the only time voters see Harris and Trump go head to head before the November general election.
WASHINGTON — In one week, Vice President Kamala Harris and former President Donald Trump will face off in a highly-anticipated debate.
The showdown will be the first major test for both candidates with voters who may be freshly tuned in to the election after Labor Day.
Traditionally, the last two months of the election tend to be some of the most important, when most undecided voters make up their minds and when early voting begins in many states.
The debate is especially noteworthy because one of its participants wasn't at the last one.
Harris is the Democratic replacement for President Joe Biden, who dropped out of the race and gave her an endorsement weeks after a disastrous June debate raised serious questions about the current president's candidacy and fitness for another four years in office.
When is the debate between Harris and Trump?
The debate is scheduled for Tuesday, Sept. 10 at the National Constitution Center in Philadelphia. It is scheduled to begin at 9 p.m. Eastern.
How can I watch the presidential debate?
ABC will host the debate, and it will air live on the network. The debate will also air on other network and cable channels, similar to the first debate between Biden and Trump.
It will also be livestreamed on the ABC News app, Disney+ and Hulu.
Who is moderating the presidential debate?
ABC's managing editor and "World News Tonight" host David Muir and ABC News anchor Lindsey Davis will moderate the debate. It's unclear if they will take a more active role in the debate. CNN anchors Jake Tapper and Dana Bash were criticized after the Biden-Trump debate for not pushing back on false claims made by the candidates.
Will there be another presidential debate?
At this point, it's unclear if this will be the only debate between Trump and Harris. The former president proposed two others, with Fox News and NBC as hosts, but Harris did not immediately agree to those dates and the Wednesday, Sept. 4 deadline for Trump's proposed Fox debate appears to be passing without any plans being formalized.
It's likely that both camps are waiting to see how the Sept. 10 debate plays out before committing to more head-to-head contests.
