The massive military parade that President Donald Trump has long wanted is set to step off from the Lincoln Memorial on Saturday evening, with tanks, bands and thousands of troops. And the biggest question marks are whether it will be overshadowed or delayed by either the weather in Washington or planned protests elsewhere around the country.

President Trump is hosting a parade celebrating the 250th anniversary of the U.S. Army today, bringing tanks and soldiers to the streets of Washington, D.C., for the capital's first major military parade in more than three decades.
