A late afternoon downpour drenched the capital's Independence Day crowds and Trump's speech unfolded in occasional rain. The warplanes and presidential aircraft he had summoned conducted their flyovers as planned, capped by the Navy Blue Angels aerobatics team.

By adding his own, one-hour "Salute to America" production to capital festivities that typically draw hundreds of thousands anyway, Trump became the first president in nearly seven decades to address a crowd at the National Mall on the Fourth of July.

Protesters objecting to what they saw as his co-opting of the holiday inflated a roly-poly balloon depicting Trump as an angry, diaper-clad baby.
