Looks like Steve Simpson's buddy John Ruble (you know, the one arrested for domestic violence that Simpson sprung from jail without a judge's order or bail) is repaying Simpson for his efforts by hosting a fundraiser for him. You may not know that immediately, though, because you'd be looking for the name "John Ruble" on the invite, and it's not there. Instead, Ruble is giving the money through his company, Jadot Construction.
Here's Jadot Construction's Certificate of Formation, showing Ruble as the manager and registered agent:
