From a report at the link below:
Rand Paul (pictured) seems to revel in frustrating fellow members of the Senate — and that makes his blatant disregard for the chamber’s chummy protocols even more infuriating to them.
Paul, the junior senator from Kentucky, appeared to thumb his nose at fellow Republicans Thursday night when he posed for a picture with conservative Reps. Justin Amash (R-Mich.) and Thomas Massie (R-Ky.) just off the Senate floor.
“Paul is the perennial annoying gadfly with no positivity associating with it. What he did didn’t change the outcome. He’s all about grandstanding,” said a Senate Republican aide.
“Taking selfies with Justin Amash and Thomas Massie — he just is the perennial annoyance,” the aide added. “He’s here to go on television and that’s what he kept doing. It’s about self promotion.”
