Under the Constitution’s 20th Amendment, the newly elected president of the United States takes office on Jan. 20 (unless that’s a Sunday, in which case it moves to Jan. 21). For Trump’s (second) big day, the pomp and circumstance will include performances by Carrie Underwood and the Village People, a military parade, and formal balls.

Will Trump take the opportunity this time, in his second inaugural speech, to talk of unity? Or will it be more 'American carnage'?
