Former House Speaker Newt Gingrich said Thursday the American people deserve answers on whether the top levels of the Justice Department and FBI were "corrupted" in 2016. 

Gingrich reacted on "Fox & Friends" to the closed-door testimony to lawmakers by FBI agent Peter Strzok, who's been accused of showing bias against President Trump in text messages to a then-FBI lawyer with whom he was romantically involved. 

"The American people, not just the Congress, deserve to know who were doing these things and what they were doing. Nothing I’ve seen so far would lead me to have any belief, except they were remarkably prejudiced and they were dedicated to Hillary Clinton winning and they were dedicated to stop Donald Trump if they could," he said of the alleged bias against Trump. 

Speaking on "The Story" Wednesday, House Judiciary Committee Chairman Bob Goodlatte (R-Va.) said Strzok's lawyers instructed him not to answer "many, many questions."

Gingrich asked whether Strzok was "deliberately avoiding discovering anything" as one of the top investigators on the Hillary Clinton email investigation. Strzok was later dismissed from Special Counsel Robert Mueller's team when he learned about the text messages.

He said Strzok and others could have been "totally prejudiced" without committing a crime, arguing "something sick" was going on when it came to disparate treatment of Clinton and members of the Trump team.
