Of course I can't provide you with proof. I didn't handle the case, so I don't have documents or access to testimony. I base it on the outcome of the case and what I hear from people I've known for 15 - 25 years who are or have been close to him. I've never spoken to Paxton himself about any of it. I've talked to him a few times over the years, but it was always about legislation and only for brief periods (maybe 20 minutes at a time). He's kind of a weird guy and not very chatty.
Wouldn't bug me if Phelan's career was over. He is a mediocre speaker and not particularly conservative - like Joe Straus was. I also know Texans for Lawsuit Reform was a pretty big advocate for impeaching Paxton (especially behind the scenes). Other than perhaps the beer distributor lobby, there's probably no special interst group I despise more. To me, they're on a level with the public school lobby.
