 Tonight, the historical presidential debate a short time from now will carry it on ABC Live. President Biden and former President Trump about to face off in Atlanta. President Biden arriving late today and Donald Trump arriving just moments ago. A rematch four years later, both ready to make their case before the American people tonight. The first debate between a sitting president and a former president. Strict rules in place tonight. No audience. The mics muted when it's not their turn to talk. Our team is all here tonight.
