Former CIA director Michael Hayden said Wednesday that Hillary Clinton’s use of an unsecure email server while working as Secretary of State was "dangerous to the republic and state secrets."
"Number one, put legality aside for a second, it's stupid and dangerous," Hayden said of Clinton’s old email habits.
"Dangerous to whom?" MSNBC host Joe Scarborough asked.
"Dangerous to her," Hayden said. "And to the republic and to American secrets. But I don't even think it was legal. That has to be against policy."
Hayden said that Clinton, or at least her staff, should have known better than to go outside of secure government channels to communicate about high-level business.
"I'm stunned that her staff allowed her to do that in 2009 given the unhappy outcome that this guaranteed once you started doing that," Hayden said.
The FBI has launched a criminal investigation into Clinton’s private server, which was found to contain highly classified spy information despite the candidate’s claim to the contrary.
A Monmouth University poll found that a majority of Americans want the criminal probe into Clinton’s email use to continue.
