Fox News was one of a few media networks to receive threatening letters on Wednesday.
Fox News host Bret Baier did a report about the letters during his evening show, "Special Report." He said that the Fox News headquarters in New York City received one such letter, which included a warning that said some envelopes could contain a lethal pathogen. The letter would also include the return address, "The MIB."
Reports indicate that the letters were sent from Portland, Oregon.
