Willett is a justice on the Texas Supreme Court, but is perhaps just as well known for his avid Twitter habit--he describes himself in his Twitter bio as "Texas' Tweeter Laureate." One of his tweets from June 2015 had a prescient haiku:
Donald Trump haiku-- / Who would the Donald / Name to #SCOTUS? / The mind reels. / *weeps--can't finish tweet*
Before joining the court, he was a deputy attorney general for the state of Texas. He also worked for then-Texas Gov. George W. Bush's administration, as well as for his 2000 presidential bid. In his youth, Willett rode bulls in the rodeo.
