Washington is hot on Thursday as thousands are gathering in the downtown for the country's annual birthday celebration which, along with traditional fireworks, will also feature battle tanks, armoured vehicles, a flyover of war planes and possibly Air Force One, as well as President Donald Trump's "Salute to America" speech this year.
But Mr Trump said the slip-up was due to a technical failure.
The event featured a flyover from the Blue Angels, as well as performances from the Army Band and the Marine Corps Silent Drill Team.
"The firefighters, first responders, police, sheriffs, ICE, border patrol - and all of the fearless men and women of law enforcement".
The speech was followed by a concert on the US Capitol lawn at the opposite end of the National Mall.

"We celebrate our history, our people, and the heroes who proudly defend our flag: the courageous men and women of the United States Military", Trump said.
Flights will be suspended at nearby Reagan National Airport from 6:15 p.m.to 7:45 p.m. ET and then again later in the evening for the festivities.
Critic Medea Benjamin said: "This is costing us millions and millions of dollars".
Trump is pushing back against complaints about the cost of the extravaganza, saying the expenses "will be very little compared to what it is worth". Fireworks are donated by two of the greats.
