Thanks for posting all of these pix – couldn’t make the rally, so appreciate your coverage.
What do we know about this guy who rushed the podium? I’m quite sure, of course, that the wingnut gallery is gearing up to say he was a plant, that the speakers planned for this to happen, etc. It would be nice to have the facts about who he is so those allegations can be nipped in the bud.
Glad no one was seriously injured.
Great pictures, Stace! I saw a lot of pictures of today’s rally opposing the elimination of the Texas HIV Medication Program, but your pictures really captured the spirit of the event. Great to see so much collaboration among different groups all pushing for better treatment for the working class, middle class, and under class.
You rock!
Old people are funny.
