A former Minnesota FBI agent has been charged with leaking classified information to a journalist, reportedly pertaining to a series of articles published by online news site The Intercept.

Terry Albury, an airport counterterrorism liaison, was charged this week by the Justice Department for “knowingly and willfully” transmitting documents and information relating to national defense to a reporter, Minnesota Public Radio reports.

He was also charged for refusing to hand over documents to the government, MPR News reports.

Albury’s attorneys, JaneAnne Murray and Joshua Dratel told Time their client was “driven by a conscientious commitment to long-term national security and addressing the well-documented systemic biases within the FBI.”
