Four Democratic candidates will take the stage in New Hampshire on Wednesday to make a final pitch to voters ahead of the state's primary contest next week.

Former Vice President Joe Biden, Massachusetts Senator Elizabeth Warren, tech entrepreneur Andrew Yang and billionaire Tom Steyer will participate in back-to-back town hall events hosted by CNN.

The cable news network will host a total of eight town halls with presidential candidates over the next two days at Saint Anselm College in Manchester, New Hampshire. The events will kick off at 8 p.m. ET each night and will be aired on CNN, CNN.com and the network's mobile apps.

During the second night, voters will hear from Vermont Senator Bernie Sanders, Minnesota Senator Amy Klobuchar, former Massachusetts Governor Deval Patrick and former South Bend, Indiana mayor Pete Buttigieg. CNN said invitations were "extended to candidates who qualify to participate in the Democratic National Committee-sanctioned debate," which will be on Friday, February 7.
