Organizers have stepped up security and readied battle tanks, fighter jets and fireworks for President Trump's Fourth of July extravaganza in Washington, D.C., per NPR.

Why it matters: July 4 has been seen as a nonpartisan occasion, but Trump has inserted himself into the event. He tweeted military leaders are "thrilled" he's honoring U.S. forces. Retired generals told Politico he's politicizing the Independence Day celebration. The taxpayer cost hasn't been disclosed, per ABC News. Here's how people have been preparing for the event in Washington, D.C., in photos.
