I noticed that his father, Fred, donated some money, on the record, to the NATIONAL REPUBLICAN CONGRESSIONAL COMMITTEE CONTRIBUTIONS fund back in 1997. You can search the federal donor list here:

I haven't found an easy way to search for donations at the Texas state level.
I also noticed the judge is a Republican.

That's not an anti-Republican statement, and I am not alluding to anything untoward. I just know that political connections breed strong cronies.
I'd be curious about what "business" dealings Fred had with Republican affiliated folks, if any.
