September's Democratic presidential debate has been narrowed to one night only, as more candidates have called it quits altogether.
Ten candidates are on stage for three-hour event hosting by ABC News and Univision, beginning at 7 p.m:
Former Vice President Joe Biden
New Jersey Sen. Cory Booker
South Bend, Ind., Mayor Pete Buttigieg
Former Housing and Urban Development Secretary Julián Castro
California Sen. Kamala Harris; Minnesota Sen. Amy Klobuchar
Former Texas Rep. Beto O'Rourke
Vermont Sen. Bernie Sanders
Massachusetts Sen. Elizabeth Warren
Entrepreneur Andrew Yang
It's the third debate of the campaign and the first time that Biden, Warren and Sanders are all together.
