The article states only that controlled Fox News is reporting their failure to cooperate.  The entire rest of the story covers other aspects...but nothing more about cooperation from prison guards - no valid info for Fox's claim - not even an unnamed source.  Looks like Fox is trying to scare other people from working with DOJ. Remember, everyone, Fox was the traitorous network which called the 2018 House for the Dems when we had only counted half the states - the eastern ones.  Shepard Smith has been promoted to where he is in more control of their content by Murdoch's liberal sons.  Sounds like BS.
