Supreme Court Justices Sonia Sotomayor and Antonin Scalia listen to the National Anthem during the 57th Presidential Inauguration ceremonial swearing-in at the US Capitol.
Hats off to Supreme Court Justice Antonin Scalia!
Four years after Aretha Franklin's headpiece stole the Inauguration Day show, Scalia got Twitter users talking with the hashtag #ScaliaWeirdHat.
Leading the charge: Senator Claire McCaskill.
What's the story behind the headpiece?
It's a gift from the St. Thomas More Society of Richmond, Va, according to University of Richmond Law professor Kevin Walsh. he wrote it was given to Scalia as a memento for his participation in one of their events. "The hat is a custom-made replica of the hat depicted in Holbein’s famous portrait of St. Thomas More."
But that explanation didn't stop others from speculating more humorous answers.
Is Scalia wearing one of those ROOTS berets from the 2002 Winter Olympics?— Ben (@benzumsteg) January 21, 2013
