Congressional investigators are reviewing 2017 testimony by Fusion GPS founder Glenn Simpson, who said that "a human source from inside the Trump organization" had "decided to pick up the phone and report something" to the FBI.

Fusion GPS is a Democrat-linked opposition research firm which produced the infamous anti-Trump "Steele Dossier," compiled from a series of memos provided by former MI6 spy Christopher Steele and paid for in part by the Clinton campaign.

Simpson told Congressional investigators on August 22 that Steele told him the FBI had corroborated parts of his dossier with "a human source from inside the Trump organization."

As the Daily Caller's Chuck Ross notes, Fusion's allies quickly began to backpedal from Simpson's statement, telling news outlets that there was no mole...

"Instead, he was referring to George Papadopoulos, a Trump campaign adviser whose encounter with an Australian diplomat in May 2016 was reportedly the catalyst for the FBI’s counterintelligence investigation. The diplomat, Alexander Downer, reportedly claimed that Papadopoulos discussed Russian dirt on former Secretary of State Hillary Clinton." -Daily Caller

That's all out the window now...

In light of last week's bombshell that the DOJ was forced to hand over intelligence to House Intel Committee Chair Devin Nunes which points to a mole within the Trump campaign, both House and Senate oversight panels are taking a fresh look at Simpson's testimony about that "human source."

In other words - did Steele tell Simpson about the FBI's alleged mole in the Trump campaign?

Simpson's lawyer said in a January letter to the Senate Judiciary Committee that his initial testimony was accurate.

Mr. Simpson stands by his testimony,” said Joshua Levy, Fusion's attorney in the January 18 letter. Levy had been asked in a January 11 letter whether Simpson’s testimony about the whistleblower (and now potential mole) within the Trump campaign was a mischaracterization, as news reports claimed.

“Glenn Simpson said that in what was closed testimony. Then it became public. Now he’s confirmed that he was telling Congress the truth, which is probably a good idea,” California Rep. Devin Nunes said on “Fox & Friends” Tuesday. “We believe he was telling the truth. And what we’re trying to do is get the documents to figure out — did they actually have, what methods were used to open this counter intelligence investigation?”

“I think if the campaign was somehow set up, I think that would be a problem. Right? If they were somehow meetings that occurred and all of this was a setup,” Nunes said, adding. “Because we have yet to see any credible evidence or intelligence that led to the opening of this investigation.”

Last month Nunes revealed that after waiting eight months for the DOJ to turn over the "electronic communication" (EC) - the document which the FBI used to launch the original counterintelligence investigation against the Trump campaign, that no intelligence was shared with the U.S. from any of the members of the "Five Eyes" agreement - that being Canada, the UK, Australia, New Zealand and the USA.

“We are not supposed to spy on each other’s citizens, and it’s worked well,” he said. “And it continues to work well. And we know it’s working well because there was no intelligence that passed through the Five Eyes channels to our government. And that’s why we had to see that original communication.”

BOMBSHELL from HPSCI chairman @DevinNunes, who says the original FBI investigation into the Trump campaign was *started* using "phony" "Five Eyes" information that "DID NOT EXIST", a "lie" from the beginning — Undercover Huber (@JohnWHuber) April 21, 2018

This is relevant because the FBI says that the Trump investigation was kicked off after Australian diplomat Alexander Downer told the FBI that Trump campaign associate George Papadopoulos drunkenly admitted in a London pub that the Russians had "dirt" on Hillary Clinton. The New York Times reported last December that "Australian officials passed the information about Mr. Papadopoulos to their American counterparts, according to four current and former American and foreign officials with direct knowledge of the Australians’ role."

This was clearly not true according to the EC, which states that no intelligence passed through Five Eyes official channels.

To summarize: it appears that the counterintelligence investigation launched against Donald Trump and his team was not based on any type of official intelligence, as many have speculated over the past year, and that the FBI had a mole in the Trump campaign - which Christopher Steele knew about.
