U.S. Defense Secretary Pete Hegseth on Friday issued orders that require journalists to have official escorts within much of the Pentagon building, the latest in a series of restrictions placed on the press by U.S. President Donald Trump's administration

The measures, which take effect immediately, bar credentialed reporters from most of the Department of Defense headquarters in Arlington, Virginia, unless they have an official approval and escort.

"While the Department remains committed to transparency, the Department is equally obligated to protect CSNI (classified intelligence) and sensitive information — the unauthorized disclosure of which could put the lives of U.S. Service members in danger," Hegseth said in a memorandum.
