Attorney General Jeff Sessions is making it clear the Department of Justice is trying to get to the bottom of the “leaks” coming out of the White House, and it will resort to new tactics, if necessary.

At a press conference Friday, Sessions said that the DOJ is taking a look at its policies for subpoenaing reporters during investigations into intelligence leaks. The announcement means that the federal government may soon require journalists to reveal their sources.

“One of the things we are doing is reviewing the policies affecting media subpoenas,” Sessions said. “We respect the important role that the press plays, and we will give our support. But, it is not unlimited. They cannot place lives at risk with impunity.”

Sessions said that earlier this year, he told the DOJ to investigate its policies on investigating leaks, and the results were concerning to him. He added that leakers will be “caught and prosecuted” by the DOJ, and lie detectors may be used, if necessary.

Also at the press conference, Deputy Attorney General Rod Rosenstein said the DOJ is in its early stages of reviewing its subpoena policy and will meet with media executives before implementing it, if it decides to.

Sessions’ announcement certainly didn’t sit well with NBC’s Chuck Todd, who said on Twitter that he would ignore the subpoena if the new policy goes into effect.

The same applied to journalist Mike Cernovich, who said he would never out sources and would even risk going to jail if it came to that.

The ACLU also chimed in on the DOJ’s announcement, saying that every American “should be concerned about the Trump administration’s threat” to clamp down on whistleblowers.

After the ACLU’s statement, Chelsea Clinton showed that she supported the press by saying she “just donated” to the ACLU.
