Special counsel Robert Mueller’s team “ought to release the 70 hours of tape” they have of interviews with President Donald Trump’s former attorney Michael Cohen, Newt Gingrich said Thursday.

The former House Speaker said that Cohen, who was sentenced to three years in prison after pleading guilty in federal court, may have told “many different stories” before “he finally got to the one that Mueller liked.”

"They ought to release the 70 hours of tape of their interviews with Cohen," Gingrich said on Fox News’ “Fox & Friends” on Thursday. “They've been using very strange prosecutorial tactics."

He added that Mueller’s team put former Trump campaign chairman Paul Manafort in solitary confinement, "basically saying, 'You get to come out of solitary when you tell us the story we like.’ They listened to Cohen for 70 hours. I'd like to know what they said to him. I'd like to know how many different stories he told until he finally got to the one that Mueller liked."

He added that prosecutors can “brutalize and demonize” a person, and said, "I have a simple test for them: Release the 70 hours of tape of Cohen's interviews. Let the country judge which story is really true and what you did to get him to say something."
