The parade is expected to include about 6,600 soldiers, 50 helicopters and 60-ton M1 Abrams battle tanks, as well as possibly 200,000 attendees and heightened security to match.

The"No Kings" protests are planned to oppose what they see as Trump's power grab. The number of planned events is nearly double that of the April 5 "Hands Off" protest that saw millions of Americans turn out in big and small cities nationwide.
