Yes, but also to sue one must be able to prove injury. I don't know much about this group, but it is possible they hadn't been injured yet. Or that, knowing this was coming, they built their case months ago and have been waiting until this drops to do anything.
Not saying they're at all worthy of trust, anyone on that side of the aisle isn't, but the case would be tossed immediately if they sued before he took this action.
More than happy to help! Let me know if I can answer any other questions for you
