As Washington prepares for Donald Trump’s big moment, one question remains: How many times will the U.S. president-elect tweet at his inauguration day?

On the eve of his presidential inauguration, Trump swept into Washington—with fireworks heralding his big moment—and vowed to unify a nation that has been divided and clamoring for change. In his speech at the celebratory evening concert on Thursday night, the real estate mogul and reality television show star said, “We are going to make America great again. And I’ll add, greater than ever before.”

Trump is the first person in the United States to be elected president without having prior experience in public office.
