Hey Pal, I don't know what you've done to protect and defend the Constitution in your lifetime so I will not question your patriotism.  But I can tell you that there is no law or First Amendment right to be a prick just because you've been issued press credentials.  So, perhaps you can explain what POTUS should have done when he's given the answer he is going to provide - even follows up and tries to move on but some douche with press credentials will not yield the microphone so a different journalist can be given the opportunity to ask a question for their news agency.  Or should POTUS have just stood there and answered this yammering douchebag's questions nonstop until little Jimmy ran out of steam?  Is that what you've been led to believe a 'free press' means?
