Biden falters in high-stakes debate, Trump spews falsehoods
The contest was seen as a test of each man's fitness for office.
In a historic clash of personality and policy, Joe Biden and Donald Trump took the stage for the first presidential debate of the 2024 election.
The showdown provided a rare opportunity for both candidates to move the needle in what has been a stubbornly tight race for the White House, but at the end of the night, Biden's halting performance raised new concerns among Democrats and cause Republicans to celebrate.
The debate was a rematch for Biden and Trump, who faced each other twice in 2020, but a first-of-its-kind format and a vastly different political landscape presented new challenges for the two rivals.

Muted mics and other new ground rules for tonight
For the first time since the first televised debate between John F. Kennedy and Richard Nixon in 1960, there will be no live audience at CNN's studio in Atlanta.
The candidates' microphones will be muted unless it is their turn to speak. They will have two minutes to respond to questions and one minute for rebuttals, and there will be a red flashing light to indicate to them their time is about to expire.
The 90-minute program will have two commercial breaks, but Trump and Biden won’t be able to consult with their teams during them. No props or note cards are allowed on stage.
Here's what experts said about the new rules, and how they may help or hurt each candidate.
Possible VP picks on hand to support Trump at debate
Several possible vice presidential picks for Trump are in Atlanta for the debate.
Sens. Marco Rubio, R-Fla., Tim Scott, R-S.C., and J.D. Vance, R-Ohio, Rep. Elise Stefanik, R-N.Y., and former Housing and Urban Development Secretary Ben Carson were seen in a picture posted to X by Stefanik.
Trump has repeatedly teased an announcement of who will join him in the 2024 ticket, but he has yet to make a final decision.

"I'd like to see what they're going to do for small businesses in this country," said Scranton resident Jennifer Merceau, whose husband owns a masonry company.
Janee Johnson, who works at Toast 'N Jams in Muskegon, Michigan, said the focus should be on doing the "right things for America."
Michael Kordecki, the owner of that restaurant, wishes he could tell the candidates to "be more positive about America, about our future, and about what we can do with or without new people coming into the country."

This is the earliest presidential debate in history
With 131 days until Election Day, this faceoff is occurring months ahead of the usual fall timeline.
"The combination of having so many people with doubts about both candidates, coupled with the first debate occurring before either convention, heightens its potential importance," Republican political strategist Whit Ayres told ABC News.
Veteran Democratic strategist James Carville told ABC News: "People's attitudes are very fixed and voters tend to be pretty entrenched. The person that 'wins' ... in this debate is going to be the one that provides voters with some new information."

Trump makes false claims Democrats support killing babies after birth
During the debate, Trump claimed that Democrats "support abortion up to and even beyond the ninth month," and contended that some Democratic states have had such a stance.
Democrats have never advocated for killing a baby after it is born as this would be murder, which is illegal in every state. Nine states have no abortion restrictions in place; however, it should be noted that late-term abortions are exceedingly rare, representing 1%, according to KFF.
