Donald Trump accused Sunday night's moderators, Anderson Cooper and Martha Raddatz, of being unfair regarding Hillary Clinton's private email server during the debate saying it seemed to be "one on three" in the hall.
After a heated discussion about Clinton's deleted emails from her private email server, he asked Cooper why he has failed to press former secretary on the issue.
"Why aren't you bringing up the emails?" Trump asked. "I'd like to know."
"You brought up the emails," Cooper said, moving on to the next questioner.
"One on three," Trump fired back.
