The seat was Judge William Thomas's, until it wasn't. He was approved by both Florida senators, vetted, and appeared set for the nomination to replace now-Eleventh Circuit Court of Appeals Judge Adalberto Jordan. Sen. Marco Rubio (R-FL) had a change of heart and blue-slip blocked the nomination, allegedly due to Judge Thomas's "judicial temperament" and doubt about his ability to hand out fair sentences.
Many believe the move was political, and due to Judge Thomas's sexual orientation.
There won't be a change of heart, it seems, as the district court seat is now set to be filled by Judge Robin Rosenberg (not to be confused with Judge Robin Rosenbaum, who was recently nominated to the Eleventh Circuit Court of Appeals bench after a few years with the district court). She comes to the federal court from the state court bench.
