“The Trump Administration will not tolerate illegal leaks of classified information that, when reported, pose a grave risk to our Nation’s national security and the brave men and women who are serving our country.”
According to the Washington Post, the alleged leaker is Aurelio Perez-Lugones, a system administrator who has a top-secret security clearance.
An FBI affidavit accuses him of accessing and taking home classified intelligence reports from secure government facilities that were later found in his lunch box and his basement.
Trump appeared to address Perez-Lugones’ arrest in an Oval Office meeting, calling him a “very bad leaker” and they would be in prison for an extended period of time.
“The leaker has been found, and is in jail right now,” he said.
“There could be some others that we are looking at, and we are hot on their trail.”
The Washington Post claims it was issued with a subpoena seeking information surrounding Perez-Lugones and asked the company to hand over communications between him and other employees.
