The Department of Justice has more than two dozen investigations into classified leaks of information, Attorney General Jeff Sessions said Tuesday.

The attorney general testified before the House Judiciary Committee and told lawmakers that 27 investigations are underway.

“We intend to get to the bottom of these leaks. I think it has reached epidemic proportions,” Sessions said. “It cannot be allowed to continue, and we will do our best effort to ensure that it does not continue.”

The number of investigations into classified leaks is a three-fold increase from those pursued by former President Barack Obama’s administration during his second term. Sessions told lawmakers there were nine open investigations of classified leaks in the last three years.

The Trump administration has been plagued by leaks ranging from details of the inner workings of and conflicts within the West Wing to the transcripts of President Trump’s phone calls with foreign leaders.

Trump has been vocal in calling for government workers who leak information to be punished.
