Former CIA Director John O. Brennan joined Twitter back in September but never used his account until Thursday and when he broke his silence, it was to slam President Donald Trump.

First, Brennan remembered the victims of the terrorist bombing of Pan Am Flight 103 in 1998, but his next tweet was aimed squarely at the White House.

“Trump Admin threat to retaliate against nations that exercise sovereign right in UN to oppose US position on Jerusalem is beyond outrageous,” wrote Brennan, who was appointed by former President Barack Obama. “Shows @realDonaldTrump expects blind loyalty and subservience from everyone — qualities usually found in narcissistic, vengeful autocrats.”

Brennan said that he was concerned that the Trump 2016 campaign’s interactions with Russians had placed it on a “treasonous path” and has tried to get Republicans in Congress to openly denounce Russian interference in the 2016 election. They refused.
