Trey Gowdy reveals mysterious evidence 'changed my perspective' on entire Mueller investigation

Former Rep. Trey Gowdy (R-S.C.) was initially supportive of special counsel Robert Mueller's investigation. But he revealed on Fox News over the weekend that his perspective shifted when he laid eyes on a mysterious piece of evidence.

Gowdy told Fox News host Maria Bartiromo on "Sunday Morning Futures" the evidence is FBI transcripts of conversations involving Trump campaign associate George Papadopoulos and FBI informants.

"Some of us have seen transcripts of those conversations. And I was supportive of Mueller. I was supportive of the idea to initiate, to investigate what Russia did," Gowdy said.

"But when I saw this transcript, it actually changed my perspective, because you want to think of law enforcement as being unbiased and disinterested in the outcome, as long as we just find the facts," he explained. "This really matters. When you have exculpatory information, and you don't share it with a court...then your bias begins to impact the investigation."

Gowdy, who chaired the House Intelligence Committee before leaving office in January, hinted last month that the FBI intentionally withheld "game-changer" evidence from the FISA court when obtaining a surveillance warrant against Trump campaign associate Carter Page.

It is widely believed the transcripts Gowdy referred to are exculpatory evidence. Some Republican lawmakers believe the government withheld the transcripts from the FISA court because they would have hurt the government's case for obtaining a warrant against Page.

Gowdy told Bartiromo the transcripts have the potential to persuade the public in President Donald Trump's favor.

"There is some information in these transcripts that I think has the potential to be a game-changer if it's ever made public," Gowdy said last month.

And there is the possibility the transcripts will be made pubic.

Attorney General William Barr is actively investigating the origins of the counterintelligence investigation into Trump's campaign, which heavily relied on the recorded conversations.

It would be Barr's decision whether or not the transcripts are released since Trump has given him the authority to declassify documents related to the investigation.
