WASHINGTON (AP) — A magistrate judge has barred federal authorities from conducting an unsupervised, wholesale search of electronic devices that they seized from a Washington Post reporter’s Virginia home while investigating allegations that a Pentagon contractor illegally leaked classified information to the journalist. In Tuesday’s ruling, U.S. Magistrate Judge William Porter said he will independently review the contents of Post reporter Hannah Natanson’s devices instead of allowing a Justice Department “filter team” to perform a search. Porter said he balanced the need to protect Natanson’s free speech rights with the government’s duty to safeguard top secret national security information.
