A FrontBurnervian sheds some light:
Don’t forget that Griffith and Hicks were both members of Sigma Phi Epsilon at UT-Austin. I’m not sure if they were there at the same time. But Griffith is a former Grand President of the national fraternity, and Hicks has always been a larger financial supporter of the Fraternity, so I imagine the connections run deeper than just Dallas politics.
Ah, yes. The old school tie.
