Were SEIU Members Paid to Protest at the Supreme Court for Obamacare?

Based on what we know in the past of SEIU and union tactics/ thuggery I think it’s safe to assume some members were paid to show up and protest. We know the unions have paid people int the past and also bus in protesters so it’s not out of the realm of possibilities. Heck majority of them rarely know what or why they are protesting. They just “go where we are told”!
