Rep. Andy Biggs (R-Ariz.) on Thursday previewed James Comey's upcoming testimony before the House Judiciary Committee, saying lawmakers want to get to the bottom of the former FBI director's numerous "inconsistencies."

Comey initially resisted the subpoena from committee chairman Bob Goodlatte (R-Va.), but he will appear for the closed-door testimony Friday after Goodlatte agreed that the former FBI head's remarks would be made public in their entirety.

Republican lawmakers want to ask Comey about the political bias and mismanagement they say permeated the Hillary Clinton and Trump campaign probes on his watch.

On "America's Newsroom," Biggs - a member of the House Judiciary Committee - said he wants to know why Comey "usurped" then-Attorney General Loretta Lynch's authority to write an exoneration letter for Clinton, why he pre-wrote the letter before the investigation was complete, why he leaked memos detailing multiple encounters with President Trump, and much more.

"There is a whole host of things that Mr. Comey knows and he's made statements on. Some of them haven't been consistent, so we need to get to the bottom of that as well," Biggs said.

He accused Comey of showing "hypocrisy" on leaks, since he released memos on his encounters with Trump after his May 2017 firing, triggering the appointment of Special Counsel Robert Mueller to take over the Russia investigation. 

Biggs said Comey used leaks to "manipulate the system" so that Mueller would be appointed.
