Trump's own applause group. Probably the same folks that cheered him at his press conference.
This is officially creepy. How long can a President behave this way before he gets chucked out? This isn't a game show. He's deliberately falsifying the reaction to his appearances. Again, like an autocrat.
"The president was able to generate a few laughs from the crowd by describing journalists as the most “dishonest human beings� while complaining about the way crowds were portrayed by the media. He then claimed that 1.5 million people were in attendance while official estimates have counted between 200-250,000.
Pool reports later clarified that the attendants who were cheering and clapping when Mr Trump spoke were not CIA staffers but people who accompanied Mr Trump to the briefing."
