Senate Judiciary Committee Chairman Lindsey Graham (R-SC) and House Judiciary Committee Ranking Member Doug Collins, (R-GA) are pushing ahead with investigations into FBI’s use of the Foreign Intelligence Surveillance Act (FISA) to conduct surveillance of former Trump campaign adviser Carter Page. Both were guests of Maria Bartiromo the host of “Sunday Morning Futures” on Fox News.

“Now I want to know, what did McCabe and Comey know, when did they know that the dossier was unreliable?” Sen. Graham told Bartiromo, referring to former FBI Director James Comey and former Acting Director Andrew McCabe. Comey has insisted that he was not aware of what was going on at the time.

“I find it hard to believe that that did not work its way up to Comey and McCabe,” he said.

To get to the bottom of this, Graham said that he wants to begin his investigation by calling the four individuals who met with the sub-source to speak to the committee.

“Did Rosenstein know that the dossier had been debunked by the time he signed the warrant? How could he not know?” Graham asked.

Meanwhile, Rep. Doug Collins spoke about the House Republicans push to amend the Foreign Intelligence Surveillance Act (FISA).

“We put this off in December because [Democrats] were in the middle of the sham impeachment and they couldn’t deal with the FISA stuff that needed to be authorized,” Collins said, referencing “things that we need in our intelligence committee,” including roving wiretaps.

“Instead of actually having hearings, and taking the Horowitz testimony, actually having Mr. Horowitz come in, talk about the problems he found in those FISA warrants, talk about how the court approved these warrants that actually spied on an American citizen… we’ve have no hearings, we’ve had no discussions and now we’re going to put forward a bill that really, I don’t think is going to address the issues,” said Rep. Collins.

Collins went on to say that if America could not trust FISA, “then people will not have confidence that our intelligence communities are doing what they need to be doing and being able to use this court properly.”
