House Speaker Paul Ryan (R-WI) speaks during a meeting with President-elect Donald Trump at the U.S. Capitol November 10, 2016 in Washington, DC. Earlier in the day president-elect Trump met with U.S. President Barack Obama at the White House.) Zach Gibson/Getty Images House Speaker Paul Ryan criticized Attorney General Jeff Sessions' insinuation that the Justice Department could subpoena journalists in its investigations of information leaks.

Sessions made the suggestion in a Friday press conference in which he outlined steps being taken to reduce the volume of leaks that have frequently embarrassed President Donald Trump and his administration.

Ryan took issue with Sessions' characterization of journalists' roles in reporting stories that include leaked information. While speaking at an event in Muskego, Wisconsin, on Friday, Ryan said it's "the problem of the leaker, not the journalist," the Journal Sentinel reported Friday afternoon.

"Leaks are concerning because leaks can often compromise national security, but that’s the problem of the leaker not the journalist," Ryan said.

Session said earlier Friday: "We respect the important role that the press plays and will give them respect, but it is not unlimited. They cannot place lives at risk with impunity. We must balance their role with protecting our national security and the lives of those who serve in our intelligence community, the armed forces, and all law-abiding Americans."

A number of press-advocacy groups, including the American Civil Liberties Union (ACLU), criticized Sessions' remarks. The ACLU's privacy, and technology director, Ben Wizner, said: "Americans should be concerned about the Trump administration's threat to step up its efforts against whistleblowers and journalists."

Citing the importance of a free and independent press, Wizner said, "leaders can't be trusted to disclose vital information that reflects poorly on themselves."
