Joey Gibson is one of the speakers who says he is coming today. He is the founder of Patriot Prayer, that's the group that was planning to speak at Crissy Field last month but cancelled because of safety concerns. He says he denounces racism and doesn't want extremists at his events, but his appearances sometimes attract them anyway.
