CNN International and CNN en Español will also broadcast the debate. It can be listened to on Sirius XM satellite channel 116.

The candidates will field questions from CNN anchor Wolf Blitzer, political correspondent Dana Bash and NY1 host and commentator Errol Lewis. Winning the state could be critical for the candidates, as 247 delegates are at stake. Clinton and Sanders both campaigned heavily in the state.

Both candidates have ties to New York. Clinton was a U.S. senator for the state for eight years, and her campaign headquarters is based in Brooklyn. Sanders, a U.S. senator from Vermont, has a distinct New York accent. He was born to a working-class, immigrant family in Brooklyn.

The debate comes as the candidates have stepped up their attacks on one another, with Sanders questioning Clinton’s voting record, corporate interests and Wall Street ties, while Clinton’s campaign has portrayed Sanders as inexperienced and unrealistic.

CNN also hosted the three Republican candidates for separate, hourlong town hall sessions, beginning Monday and running through Wednesday. Each candidate was joined onstage by their family members for the event.

Clinton currently holds 1,289 pledged delegates, while Sanders trails behind with 1,038. When superdelegates are included, Clinton’s lead widens, with 1,758 delegates, compared to 1,069.
