Trump's youngest child, Barron Trump, was a 10-year-old elementary school student when he moved with his dad and mom, first lady Melania Trump, to the White House in 2017.

One of the time-honored displays of bipartisanship after the president’s swearing-in is the inaugural luncheon in Statuary Hall. Mr. Trump, known for being consistently late to his political rallies, spoke for more than 30 minutes to an overflow crowd in Emancipation Hall after his inaugural speech. It pushed the day’s program back.

Trump began Monday with a prayer service at St. John’s Episcopal Church. Then he and his wife Melania will be greeted at the executive mansion by President Joe Biden and first lady Jill Biden for the customary tea. It’s a stark departure from four years ago, when Trump refused to acknowledge Biden’s victory or attend his inauguration.
