While more details about President Donald Trump’s Fourth of July celebration came into focus on Friday, questions still remain about the event, including whether or not tanks will be allowed on the National Mall, and who will need tickets to attend.

Trump’s “Salute to America” event on Thursday at the Lincoln Memorial will include flyovers, music, and military demonstrations. According to the Washington Post, Trump has asked to station tanks or other armored military vehicles on the Mall for his speech to the country, but those details have not been finalized.

The event will also include a ticketed section close to the Lincoln Memorial, according to an official with the U.S. Secret Service, but it’s not yet clear how that process will work, or who needs a ticket.

The Secret Service say “Salute to America” will be secured by the agency and that tickets and additional security screening will be required for the event. The agency deferred to the White House about the issue of ticketing. A spokesperson for the White House said there will be a ticketed portion for VIPs, friends and family, and members of the military, but that “the entire event is open to the general public” and the general public area does not require tickets. 

Meanwhile, a spokesperson for the National Park Service said the agency has received maps that show an area marked “general admission,” but that area also requires a ticket, which has prompted some confusion. (We’ll update as we get more information).

This year’s event comes after Trump’s request for a military parade in D.C. on Veteran’s Day last year was canceled. The President blamed D.C. leaders for the high cost estimate of the parade.
