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.

Organizers say that one march will go to the gates of Trump’s Mar-a-Lago resort in Florida, where Republican Gov. Ron DeSantis warned demonstrators that the “line is very clear” and not to cross it.

Trump vowed throughout his campaign that he would conduct the largest mass deportation in U.S. history. The showdown with Los Angeles was inevitable.

Farmers and agriculture groups, she said, were increasingly uneasy about his immigration crackdown.
