Fox News contributor and former House Oversight Committee Chairman Jason Chaffetz called for the departure of Attorney General Jeff Sessions.

Chaffetz said removing Sessions may fix the "deep systemic problems" within the Department of Justice.

"It pains me to say this a little bit [but] I don't think the attorney general is up to the job he's doing," Chaffetz said.

He criticized Sessions for not taking a more active role in rooting out recent subjects of controversy at the DOJ, including FBI Agent Peter Strzok.

The Justice Department said a senior federal prosecutor is reviewing the matter to see if a second special counsel is needed.

Chaffetz said the only reason Strzok's former supervisor, Robert Mueller, is leading a special investigation is because Sessions "had to recuse himself from everything" involving the president.

He said that in addition to Sessions' recusal, the former Alabama Republican senator told him he wouldn't prosecute Bryan Pagliano, the IT technician at the center of Hillary Clinton's email scandal, who defied a Congressional subpoena.

Sessions also reportedly refused to publicize documents on the Eric Holder-era Fast & Furious scandal, which lead to the death of U.S. Border Patrol Agent Brian Terry, Chaffetz said.

Law Professor Alan Dershowitz also told "Fox & Friends" that Deputy Attorney General Rod Rosenstein should recuse himself from the process as well.
