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.

Biden pokes fun at Trump's jabs about performance-enhancing substances

Biden posted a photo on x taking a shot at Trump's allegations that he's taking performance-enhancing substances for the debate.

The president is seen holding a can of water with the "Dark Brandon" meme image claiming to be "Dark Brandon's secret sauce." The can, which will go on sale on the Biden campaign's site next month, has a statement in bold letters "Get real, Jack. It's just water."

Joe Biden posts a photo of himself on his X account, prior to the debate with former President Donald Trump, on June 27, 2024, in Atlanta.

"I don't know what they've got in these performance enhancers, but I'm feeling pretty jacked up. Try it yourselves, folks. See you in a bit," the X post said.

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 debate will not feature an audience and microphones will be unmuted only when it is a candidate's turn to speak. ABC News' Rachel Scott reports from Atlanta.
