President Donald Trump’s lawyer Rudy Giuliani appeared on “Hannity” last night to declare his belief that it was former CIA Director John Brennan who was responsible for the entire Robert Mueller investigation.

To be more precise, it would’ve been Brennan who started the FBI counterintelligence probe into the Trump campaign, which then became the Mueller investigation after James Comey was fired.

“The reality is I’m going to tell you. We don’t have the time to go into it, we can do it later, I’m going to tell you who was the quarterback for all of this. It isn’t just Strzok. Strzok is a bit of a puppet. Then there’s Mueller, he’s a puppet. The people working for him, some of them are,” Giuliani told Hannity.

At this point, Hannity said, “I have a funny feeling you’re about to drop a bomb on me.” “Well the guy running it is [John] Brennan and he should be in front of a grand jury. Brennan took an affidavit – a dossier, unless he’s the biggest idiot intelligence agent that ever existed, although he never did much intelligence work, it’s false. You could look at it and laugh,” Giuliani replied.

Watch the full segment below:

As I outline in my new book “Spygate,” Brennan played a large role in relaying British intelligence on the Trump campaign to the FBI (a form of “information laundering,” if you will). The British intelligence agency GCHQ had been gathering intelligence on members of the Trump campaign (which they claim was accidental), but certainly, it wasn’t accidental when the head of the GCHQ, Robert Hannigan, flew down to Washington to share that intelligence with Brennan in the summer of 2016. Brennan had also received information from “an intelligence agency of one of the Baltic States” earlier in April. Brennan then was able to use the GCHQ’s (and Baltic) information to press the FBI into launching a counterintelligence investigation into the Trump campaign.

Hannigan unexpectedly resigned from the GCHQ the day of Trump’s inauguration, and I find it hard to believe that’s a coincidence.

Meanwhile, Brennan is parading himself around the media circuit to push the faux-narrative he himself helped create. In his words, President Trump’s meeting with Putin in Helsinki was “nothing short of treasonous” he told us, exceeding the threshold of “high crimes and misdemeanors.” If Trump sharing a stage with Putin is Brennan’s idea of evidence of collusion, is there anything Brennan won’t pretend is collusion?

Both Sen. Rand Paul and President Donald Trump have called for Brennan’s security clearance to be revoked, given how he’s known to abuse intelligence for his own political ends.

When Trump said that Obama spied on him, he was right. The surveillance may not have been direct, but we now know for a fact that foreign intelligence was surveilling Trump – and reporting it back to American intelligence. And is that really all that different? I’d argue it’s worse – as it means Obama tried to cover up the spying.
