At this point,it is totally irrelevant what kind of reporter Acosta is. The court is faced with a question of whether the President has the right to determine access to his work space. If he can be dictated to by a private business (CNN) so can the courts and congress. I can just see Mr. Acosta strolling into the Supreme Court and demanding to interrogate the Chief Justice.
Judge will grant CNN their wishes on Acosta.
