Department of Homeland Security employees were warned in an email Thursday not to leak any “nonpublic information” or else face “criminal, civil or administrative consequences,” according to a Buzzfeed News report.

“As federal employees, we serve the public, and our loyalties must prioritize that purpose above all others. A violation of the public trust might arise, for example, if DHS personnel disclose nonpublic information or use it for their own personal benefit, such as for monetary gain, or for the private gain of others,” wrote Chip Fulghum, deputy under secretary for management.

The “nonpublic information” would include “you know or should have known has not been made available to the general public, is designated as confidential and would not be made public even upon a request.”
