Watch when Donald Trump's wife, Melania, claps during a Trump speech when he is acknowledging various people. She is tough and doesn't always clap on cue when the rest of the crowd claps. And she certainly doesn't clap at the mention of every name.
She claps only when names are mentioned that she really seems to know. She clapped for Corey Lewandowski, Paul Manafort, when Donald mentioned them and the Trump staff. She didn't clap for others, most noticeably when Trump mentioned Sarah Palin. Also no clapping for Bobby Knight. She clapped most enthusiastically for the insane Jeff Sessions.
