This is pizzagate related because it's Hillary and Bill are connected to child trafficking.

Hillary Clinton wore a purple pantsuit at her concession speech. Bill wore a purple tie, and others wore purple. Obviously they were sending a message, a sign of 'their' cause.

Here is the HuffPOst take on why they wore purple, from loyalty, to unity between Red and Blue states, to LGBQT support. Others think it had some satanic meaning or symbolized a purple revolution.

Hillary also wore a small pendant necklace with the purple suit, but I have not seen it discussed. And from this article we know she wears jewelry to symbolize sentiments.

People give me all kinds of charms, mementos that are important to them and I do keep them with me. ... So I carry my own personal talismans around with me. But then I also carry around things that people have pressed into my hand that are important to them – a rosary, a medal, a Purple Heart medal, a prayer ring, a knitted cross, an evil eye to ward off an evil eye.

Bill Clinton also wears jewelry to signify a sentiment. He wears a hand-made bracelet given to him by the Columbian band, Los Ninos del Vallentano, whose lead was kidnapped and killed by (ahem) rebel forces a few years later. Bill has worn the bracelet ever since he was killed as a sign of solidarity with the Columbian people. Now why would Bill be showing support for the Columbian people? There has got to be more to it than that.

So, it is obvious that the Clintons wear jewelry to send messages, and they obvioulsly want people to know that is what they are doing, so what is the small pendant she wore with the purple?
Here is a pic of her purple suit and necklace. Can you tell what it is?
