Former CIA chief Michael Hayden said in a new interview that he agrees that Donald TrumpDonald TrumpTrump on Dems boycotting inauguration: 'I hope they give me their tickets' DeVos vows to be advocate for 'great' public schools Trump: 'I don’t like tweeting’ MORE has become a "recruiting sergeant" for terrorists groups such as the Islamic State in Iraq and Syria (ISIS) and al Qaeda.
“When Mr. Trump says some of the things that he has said — 'they all hate us,' 'we shouldn’t let any of those people in our country' — what he does is underscore and underpin the fundamentals of [the ISIS] narrative of undying enmity,” Hayden told Al Jazeera English's "Upfront."
Trump's statements "have already made Americans less safe," Hayden said in the interview, which will air April 1.
Last week, ISIS released a new recruitment video featuring Trump and calling for jihad after the March 22 terrorist attacks across Brussels that left at least 35 dead and wounded more than 300.
A newspaper linked to al Qaeda in the Arabian Peninsula, meanwhile, published a report on Tuesday that said Trump is the "clearest in expressing the American opinion about Islam, but he lacks political experience," according to The Wall Street Journal.
The former National Security Agency director and retired Air Force general also said fellow Republican presidential candidate Ted CruzTed CruzGraham, Cruz proposal to defund the U.N. is misguided Right renews push for term limits as Trump takes power Dissenting nominees give hope to GOP skeptics of Trump MORE's call for increasing patrols of Muslim neighborhoods in the U.S. is "dangerous" and could lead to "radicalized communities."
“We don't have radicalized communities in the United States,” Hayden said. “We have some radicalized individuals, but we have it fully within our ability to create radicalized communities, and that kind of rhetoric … actually bends you in the direction of radicalizing communities.”
Hayden also weighed in on the Democratic front-runner Hillary ClintonHillary Rodham ClintonTrump puts pressure on GOP Congress Poll: Former Sanders staffer gains steam in race to replace Xavier Becerra Michael Moore: Trump will ‘absolutely’ ban Muslims MORE, saying he believed that her personal email account, which she used for work during her tenure as secretary of State, was hacked by foreign intelligence agencies.
"Yeah. And by the way, I would move heaven and earth as the director of the NSA to get the unclassified emails of several foreign ministers," Hayden said.
Hayden added that he “would lose respect for scores of intelligence organizations around the planet if they weren’t already thumbing through the emails."
He said Clinton's home email server "was wrong" and that her explanations "are incoherent."
"It was a terrible mistake," Hayden said
"Whether or not it represents a crime, I'll let the American justice system decide," Hayden said.
