(CNSNews.com) - Former Deputy/Acting FBI Director Andrew McCabe -- the man who opened the counter-intelligence investigation into President Donald Trump -- said the Mueller report did not resolve "all of the questions and issues surrounding that investigation."
McCabe told MSNBC's Rachel Maddow Thursday night that Mueller's focus was "fairly narrow," involving coordination between the Trump campaign and the Russian government.
Mueller did not examine whether President Trump is compromised by a foreign power, and McCabe indicated the FBI may still be looking into that.
"We'll have to wait and see what actions, what investigative actions, the FBI takes -- if, in fact, any of the actions are ever shared with the public."
McCabe said Mueller was careful to stay within the "guide rails" the Justice Department gave him:
And I think that was an appropriate way to conduct the Special Counsel's business.
That does not completely eliminate every possible suspicion, every curiosity, every concern that counter-intelligence investigators would have about a high-level government executive, someone -- not even the president of the United States, but anybody with access to the sort of material that the president has access to -- who also has a history of interactions and dealings with Russians of questionable background, with individuals who have -- surrounds himself with people who have contacts to sanctioned entities or to...people with backgrounds in Russian intelligence.
Those are the exact sort of flags that you look for in a counter-intelligence investigation to determine is this person, the principal -- in this case, the president of the United States -- somebody who would be subject to influence from a foreign power, or is it someone who actually might even have some sort of relationship with a foreign power?
Maddow asked McCabe, "Do you have any sense as you sit here now as to what happened to that (foreign influence) investigation?"
"The question as to whether or not all of the questions and issues surrounding that investigation were resolved by the Mueller report, I think is fairly obvious. They were not," McCabe said.
"Will we ever see a resolution to those questions? I don't know. We'll have to see. We'll have to wait and see what actions, what investigative actions, the FBI takes -- if, in fact, any of the actions are ever shared with the public."
Maddow told McCabe that many people thought the question of foreign influence had been folded into Mueller's investigation. "We have this detailing of the contacts but no statement at all as to what the conclusion might be as to potential compromise," Maddow said.
She asked McCabe if the House or Senate intelligence committees are entitled to get a briefing on the FBI's counter-intelligence investigation into Trump -- "whether it's resolved or whether it's open," she said.
"In my experience, Rachel, we were very careful to keep the intelligence committees in the House and Senate up to speed on the most significant investigations we were pursuing. This is certainly one that would fall within that realm," McCabe said.
Preceding McCabe on Maddow's program, Rep. Mike Quigley (D-Ill.) said the House intelligence committee, on which he sits, is pursuing an investigation into whether Trump is compromised by a foreign power. "The American public needs to know we are still on that," Quigley said.
"The House Select Committee on Intelligence continues that work through the subpoena process. The Justice Department just released some of the documentation to us. But we are ready to proceed if at any point they stop cooperating.
"It is extraordinarily important for folks to know that Mueller thought that most of that was outside the scope of his investigation. But it's fair for us to ask whether the president of the United States was compromised. And frankly, I believe he was," Quigley said.
