John Schindler, a former National Security Agency analyst and current columnist for the New York Observer, said Wednesday that the intelligence community will go “nuclear” against President Donald Trump.

The national security columnist also quoted a senior intelligence official telling him that Trump “will die in jail.” “Now we go nuclear. [Intelligence community] war going to new levels. Just got an [email from] from senior [intelligence community] friend, it began: ‘He will die in jail,'” Schindler tweeted.

The Observer columnist has for months taken a strong stance against Trump. He recently wrote an article called “The Spy Revolt Against Trump Begins.” (RELATED: Rep King: Leakers In Intel Community Have To Be ‘Purged’)

This came after President Trump angrily tweeted about continued leaks to major media outlets. “Information is being illegally given to the failing [New York Times] & [Washington Post] by the intelligence community (NSA and FBI?). Just like Russia,” Trump wrote. (RELATED: Journalists Go Nuts Over Rehashed New York Times Story)

Schindler received heat for his tweet suggesting a coup by the intelligence community.

ABC News chief foreign correspondent Terry Moran tweeted, “If this source is for real, talk of a ‘Deep State’ coup aren’t insane. [The president] will ‘die in jail’? Who do you think you are?”

The former NSA analyst stood by his comment and said, “Surprisingly, some US spies consider [the president] colluding with [Russian intelligence services] + Kremlin, [including] election theft, to be kinda treason-y.”
