Haven't heard a thing about a criminal investigation.
I also have to retract part of my response. There was talk early on about the Texas AG(?) looking into the matter since at least some of the chicanery was apparently conceived in our fair state. Haven't heard a whisper since FWIW.
Now, I'm no legal beagle, but this smells of high crimes; fugitabout misdemeanors! It's as if their internal investigation will the final word. Worrisome.
