Brennan had to, and still has to, feel he is untouchable. This is the same guy that had his CIA operatives spy on Senate staffers when he was head of the CIA. He lied about, then was forced to confess the truth. This should have meant a jail sentence for him but he escaped with no punishment, not even a slap on the wrist. Now Brennan has been caught lying to congress about the Steele dossier. The guy continues to go on TV and lie to the American people and network like CNN protect him and give him a platform. In an environment like this, the corrupt feel free to act, out in the open. When they say no one is above the law, the know their side is, in fact, above the law.
Brennan is low hanging fruit for the DOJ. There is video of him telling congress that the Steele dossier had little to do with the decisions to proceed with the Russia collusion investigation.
And btw, do you all remember when Brennan was testifying about how the Russia collusion investigations started? He said he got word that there were Trump campaign associates who were making contact with Russian operatives and he was worried that the Russian were trying to turn them, or use them. So he took it upon himself to contact the FBI. But it never occurred to him to give the Trump campaign a heads up that the people they were speaking to might be Russian agents. Do you all recall that?
