This seems a little incongruous, doesn't it? Shouldn't they attempt to be occupying some part of D.C. instead if that is their goal?
They may be championing some actual cause, but they have not articulated it well. Both the reasoning and the demands seem very unclear for a protest that is to occur two days from now.
