In a blistering tweet, Brennan blasted Trump for celebrating the dismissal of former FBI deputy Director Andrew McCabe.
Trump would take his “rightful place as a disgraced demagogue in the dustbin of history” once “the full extent” of his “venality, moral turpitude, and political corruption becomes known,” Brennan wrote.
“You may scapegoat Andy McCabe,” he added. “But you will not destroy America… America will triumph over you.”
Attorney General Jeff Sessions fired McCabe from his role on Friday, just two days before he was slated to retire, over his alleged conduct during a review of an investigation into the Clinton Foundation.
Brennan’s tweet was in direct response to an earlier post from Trump, shortly after midnight, in which the president described McCabe’s firing as “a great day for the hard working men and women of the FBI” and “a great day for Democracy.”
McCabe has already hit back at his dismissal via a lengthy statement.
“This attack on my credibility is one part of a larger effort not just to slander me personally, but to taint the FBI, law enforcement, and intelligence professionals more generally,” he wrote. “It is part of this Administration’s ongoing war on the FBI and the efforts of the Special Counsel investigation, which continue to this day.”
Earlier this month, Brennan said there was “deep, deep worry and concern” about America’s safety under the Trump administration.
