How to Watch Tonight’s Democratic Debate

Democratic presidential candidates will square off this Sunday for their fourth debate—and it will be streamed online for free.

NBC and the Congressional Black Caucus will host the event in Charleston, South Carolina. TIME will have a live stream available on the web, starting at 8pm Eastern.

Hillary Clinton, Bernie Sanders and Martin O’Malley will once again stake their claim for the Democratic presidential nomination. O’Malley almost didn’t qualify for the debate, while Sanders and Clinton are embattled in a divided contest for the early primary states of Iowa and New Hampshire.

NBC’s Lester Holt will moderate the event, which will take place at the Gaillard Center—not far from the site of the mass shooting at Emmanuel African Methodist Church.

The debate starts at 9pm Eastern on NBC and can be streamed here. Recap moments from the last debates above.
