(AP) - Police say the Green Party candidates for president and vice president have been arrested at the second presidential debate.

Nassau County, N.Y. police say Jill Stein, the Green presidential nominee, and Cheri Honkala, the vice-presidential nominee, were charged with disorderly conduct as they tried to enter the debate site at Hofstra University.

The Green Party says in a statement that Stein and Honkala were walking with supporters toward the Hofstra campus Tuesday afternoon when they were met by uniformed police officers. Stein and Honkala then held an impromptu press conference in which Stein called the debate a "mockery of democracy."

A third person was later charged with disorderly conduct.
