Former House Oversight Committee Chairman Jason Chaffetz, Saturday called for Attorney General Jeff Sessions to be removed from office, saying that may be a cure for the "deep systemic problems" in 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, now a contributor for Fox News, told the "Fox and Friends Saturday" program.

Sessions "had to remove himself from everything" involving President Donald Trump and that led to the appointment of Robert Mueller as special investigator in the investigation into Russian meddling in the 2016 election, said Chaffetz.

He also criticized the attorney general for not taking on a more active role in digging up information about several controversial figures at the DOJ, including Agent Peter Strzok, who was removed from the investigation after a series of anti-Trump text messages between him and a fellow agent were discovered.

Chaffetz said that Sessions also had told him that he would not prosecute Bryan Pagliano, Hillary Clinton's former chief tech staffer, who had refused a Congressional subpoena to testify about the 2016 Democratic nominee's use of a private email server.

Sessions had also refused to make documents on the Fast and Furious scandal public following the death of U.S. Border Patrol Agent Brian Terry, Chaffetz said.
