So, if CNN has a magic right to be in the White House, under 1st and 5th Amendment Rights, then I have a magic right to go on their network anytime I want. If they say no, then, I could sue them for violating my 1st and 5th Amendment Rights.
You must be a victim of the government runs school system. The 1st and 5th Amendments protect us from the government and have no application to private entities like CNN.
