Brennan is LOUD
Criticism of Trump administration
Since leaving office, Brennan has been harshly critical of Trump. In March 2018, Brennan said Trump had "paranoia", accused him of "constant misrepresentation of the facts", and called him a "charlatan".[64] Following the firing of senior FBI official Andrew McCabe later that month, Brennan tweeted to Trump, "When the full extent of your venality, moral turpitude, and political corruption becomes known, you will take your rightful place as a disgraced demagogue in the dustbin of history. You may scapegoat Andy McCabe, but will not destroy America… America will triumph over you."[65] Axios quoted Brennan as replying on Twitter to Trump's harsh comments about James Comey (over quotes reported in advance from his April 2018 book) as, "Your kakistocracy is collapsing after its lamentable journey… we have the opportunity to emerge from this nightmare stronger & more committed to ensuring a better life for all Americans, including those you have so tragically deceived."
