Watch live: CNN Presidential Debate Simulcast Thursday 9PM EST

President Joe Biden and former president Donald Trump will face off on Thursday, a rematch of the debate cycle.

Their first debate was notably feisty, with both candidates consistently interrupting each other, the second debate was canceled because Trump refused to participate remotely after being diagnosed with COVID-19, and the third debate was more tempered than the first, as the candidates discussed the response to the pandemic and racism in the country.

This year, the two candidates abandoned the Commission on Presidential Debates and agreed to earlier debates. CNN will be hosting the presidential first face-off from their Atlanta studios, and the candidates' microphones will be muted outside of their turn to speak.
