Pataki brought up Clinton's well-worn email scandal in his response to moderator Jim Cramer's question about cyber warfare.
"Jim, I got to tell you something talking about cyber security. Hillary Clinton put a server, an unsecure server, in her home as secretary of state," Pataki said. "We have no doubt that that was hacked and that state secrets are out there to the Iranians, the Russians, the Chinese and others. That alone should disqualify her from being president of the United States."
