The commentary comes after Attorney General Jeff SessionsJefferson (Jeff) Beauregard SessionsSessions: 'We should be like Canada' in how we take in immigrants DOJ wades into archdiocese fight for ads on DC buses Overnight Cybersecurity: Bipartisan bill aims to deter election interference | Russian hackers target Senate | House Intel panel subpoenas Bannon | DHS giving 'active defense' cyber tools to private sector MORE announced a crackdown on leaks that have plagued the Trump administration on a regular basis since taking office in January.

"[Rod Rosenstein] comes with absolutely zero credibility on this," said Chaffetz on Fox's "America's Newsroom."

"I asked him if he looked at Hillary ClintonHillary Diane Rodham ClintonIntel Dem decries White House 'gag order' after Bannon testimony 'Total free-for-all' as Bannon clashes with Intel members Mellman: On Political Authenticity (Part 2) MORE whether she told the truth under oath. He said he needed a request from Congress. Myself and the chairman of the Judiciary Committee to the department of justice. It has never been answered."

"Let’s start with Hillary Clinton and whether or not she lied under oath and go back to the State Department who had an open investigation," the Fox News contributor continued. "They reopened it July 7th of 2016. Nearly 300 people who are dealing in classified information in a nonsecure setting, why didn’t they ever close that investigation? They need to answer those questions. Start with that. They come with zero credibility on this issue."

Sessions announced Friday a governmentwide crackdown on leakers and put the media on notice that it "cannot place lives at risk with impunity."

"We respect the important role the press plays and we’ll give them respect, but it’s not unlimited,” Sessions said. “They cannot place lives at risk with impunity. We must balance the press’ role with protecting our national security and the lives of those who serve in the intelligence community, the Armed Forces and all law-abiding Americans.”

President Trump praised Sessions on Saturday for cracking down on leaks, a shift from Trump's recent criticism of the Justice Department head.

"After many years of LEAKS going on in Washington, it is great to see the A.G. taking action! For National Security, the tougher the better!" Trump tweeted Saturday.
