Was he required to? What does who he is have to do with the question?
He’s requesting an interview, a filmed recording of the congressman’s response.
The congressman should not have touched him. The kid could have given his name. He should not have expected a reply unless he was willing to give his name. He’s the one who approached the congressman, not the other way around. All this business about “rights” is stupid. The kid wants an interview. He wants to play “journalist.” Well, let him be a decent, normal person about it.
