President Trump and former VP Joe Biden will face off Tuesday for the first of three presidential debates.
They'll share a socially distant debate stage, and skip the customary handshakes, organizers say.
Both campaigns view the 90-minute televised event as a critical opportunity to sway undecided voters.
Experts say Biden must stop Trump from creating big moments that appeal to his base and control the media narrative afterward.
Trump and Biden are sure to argue that the election will impact the direction of the Supreme Court for decades
Biden has prepped in closed-door mock sessions, while Trump says his practice has been less formal.
"You know what I do is debate prep every day. I'm taking questions from you people all the time." -Donald Trump
"I'm prepared to go out and make my case as to why I think he’s failed and why I think the answers I have to proceed will help the American people." -Joe Biden
