The tentative deal reached this weekend between the presidential campaigns of Hillary Clinton and Bernie Sanders includes a debate Thursday at the University of New Hampshire in Durham.

MSNBC announced Sunday it will host the debate, scheduled for 9 p.m. Eastern with Chuck Todd and Rachel Maddow moderating. New Hampshire's first-in-the nation primary is Feb. 9.

Clinton and Sanders are in a tight race before Monday's Iowa caucuses, and Clinton trails the Vermont senator in New Hampshire, raising the possibility that the Democratic front-runner could lose the first two contests. Former Maryland Gov. Martin O'Malley has trailed them by wide margins.

The Democratic National Committee says it's reached an agreement in principal to have the party sanction and manage more debates during the primary schedule, including the New Hampshire debate.
