Chances are good that she didn’t voluntarily surrender her law license, it was probably suspended by the State Bar Assoc (the gawds that be). How she can continue to actually function in office is beyond me, I think you need JD after your name to issue warrants. So maybe her associates are doing all the work, and she’s just sitting in her office, collecting her pay and most importantly, racking up that retirement plan.
I haven't read anywhere that she surrendered her law license. She did lose her driver's license for 180 days.
In looking at “texas sentencing for DWI” I find that 72 hrs in jail and a fine if most common or recommended. So why did she get over a month? And yes the court ordered her to give up her license, but if every lawyer caught drunk had the same sentence the state bar would be having some new rules>
