Former Vice President and now candidate for president, Joe Biden, is seen waving to a reporter who wants him to come talk. The reporter said, "Mr. Vice President, come talk to us" and Joe Biden gives a wave and keeps walking.
Did Joe Biden hear what she said or not? Dunno. Did he hear her and not want to talk? Dunno.
Would Trump have stopped to talk? Possibly, since he loves free press and being on camera and creating headlines.
