The first presidential debate of 2016 will be held Monday night, with NBC News anchor Lester Holt moderating the debate between Hillary Clinton and Donald Trump at Hofstra University in Hempstead, N.Y.

However, Libertarian Party candidate Gary Johnson and Green Party candidate Jill Stein will not be joining them, having failed to meet the necessary threshold on polling.

The Commission on Presidential Debates requires candidates to:

Be constitutionally eligible for the presidency;

Be on the ballot in enough states to win a theoretical Electoral College majority; and

Receive at least 15 percent support in current polling averages.

Both third-party candidates have met the first two criteria. But Johnson, with 8.4 percent in current polling, and Stein, with 3.2 percent, missed the mark on the third.

In announcing the first-debate lineup, the commission said, “The criteria will be reapplied to all candidates in advance of the second and third presidential debates,” meaning Johnson and Stein still have an outside shot to join Trump and Clinton on stage.
