Why is Brennan so nervous about the Barr-Denham investigation?

Red States:

Big news breaking in the investigation of the Russia probe by U.S. Attorney John Durham.

We’ve reported that the Durham probe had expanded, was now likely a criminal investigation and that Durham wanted to talk to both former CIA head John Brennan and former Director of National Intelligence James Clapper.

Now comes the word about what caused that expansion of the investigation from Fox News’ Catherine Herridge.

Herridge explained it was expanded because of “new evidence” that was discovered during their investigations in Rome, Italy.

Herridge reports that the Italian prime minister confirmed to his parliament that he did let Attorney General William Barr meet with Italian intelligence agents on the subject of the Russia investigation, that this was the “correct decision” and had been arranged through proper diplomatic channels. The meetings occurred August 15 and September 27 in Rome. During one of the trips, Barr and Durham discovered the “new evidence” and according to Herridge’s contacts, Durham is “very interested” to question Clapper as well as Brennan.

Fox reported some information about the meeting.

In Italy, Barr reportedly told embassy officials he “needed a conference room to meet high-level Italian security agents where he could be sure no one was listening in.”

A source in the Italian Ministry of Justice told The Daily Beast earlier this month that Barr and Durham were played a taped deposition made by Joseph Mifsud, the professor who allegedly told ex-Trump aide George Papadopoulos that the Russians had “dirt” on Hillary Clinton. Mifsud reportedly was explaining to authorities in the deposition why people would want to harm him, and why he needed police protection.

Papadopoulos has suggested he was connected with Mifsud as part of a setup orchestrated by intelligence agencies.

There are also reports that Durham now has Mifsud’s Blackberrys

Papadopoulos was allegedly the reason for opening the Russia investigation.

If there was a set-up and that’s been exposed, then it would have been a tainted effort of entrapment to start. That might explain why Brennan has been melting down of late and why he’s so upset that Durham wants to question him.

The Papadopoulos charges have always looked like a setup and it is now looking like it was one not only to entrap the guy but to use it as an excuse for investigating the Trump campaign.  With Clapper saying he was "just following orders" from President Obama, it looks like a conspiracy starting at the top to hurt the Trump campaign.
