Americans marked the nation's 250th Independence Day in the capital on Saturday amid extreme heat and a charged political atmosphere, as President Donald Trump addressed crowds at the National Mall ahead of a massive fireworks display delayed for hours by an incoming storm.

The event began after storms prompted a roughly two-hour evacuation of the National Mall just after 7 pm EDT.

Trump spoke to a large crowd inside a cordoned off area with heavy security, overlooked by the Washington Monument. Thousands more lined nearby streets, unable to get in.
