Watch Jimmy Fallon channel Bruce Springsteen to sing 'Robert Mueller's Comin' to Town'

Jimmy Fallon is bringing the Christmas spirit to politics through song. 

The Tonight Show host showed off his best Bruce Springsteen impression Monday night to give his audience a Robert Mueller-inspired version of Santa Claus Is Comin' To Town.

Robert Mueller, a lawyer and former director of the Federal Bureau of Investigation, is serving as the special counsel responsible for the investigation into collusion between President Trump's administration and Russia. 

"You better watch out, you better not cry, you better not lie to the FBI," Fallon sang. "He's making a list, naughty or nice, he's finding out just who to indict."

He continued, "He sees your Russian meetings, he's read all your emails. He knows that you tried to collude, it isn't fake news for goodness' sake."
