The posts on the Barge list have been flying back and forth with some poker player heavy hitters joining in. One person got through to a Binions' executive (unnamed) and this was a report on what she said.

I just got off the phone with a senior executive of the Horseshoe. While she
hadn't heard of the incident involving Paul, she happened to have the head
of security in her office at the moment. She confirmed with him that my
assertion about Paul getting tossed was valid, and agreed that such a
punishment did seem extreme for what amounted to exercising one's first
amendment rights. She also promised that Becky would get back to me on
Monday in an attempt for us to clear this up.
