The New York Times sued the Defense Department on Monday for the second time in five months, arguing that a requirement that journalists be escorted while on Pentagon grounds violates the First Amendment.

The escort policy is “an unconstitutional attempt by the Pentagon to prevent independent reporting on military affairs,” a Times spokesman, Charlie Stadtlander, said in an email to The Associated Press.

“As we have said before: Americans deserve visibility into how their government is being run, and the actions the military is taking in their name and with their tax dollars.”
