 Live from NPR News in Washington, I'm Corva Coleman. President Biden and former President Donald Trump will face off tonight in the first presidential debate of the general election. As NPR's Elena Moore reports, this marks a new stage of the 2024 race. The debate kicks off at 9 p.m. Eastern time. It's hosted by CNN at their studio in Atlanta. The first time in decades that a private media company is organizing a presidential debate. And the rules look different this year.
