(Bloomberg) -- President Donald Trump is getting what he wants for the nation’s birthday: a celebration featuring fireworks, fighter jets and tanks that makes him the center of attention.Trump will speak from the steps of the Lincoln Memorial Thursday evening, remaking the capital’s July 4th festivities into a display of military might mixed with presidential politics. The White House said Trump’s message won’t be political -- Trump is calling the speech a “Salute to America” -- but it comes as the 2020 campaign is heating up.The city will host a parade in the morning before the evening program on the National Mall, which will include flyovers by fighter jets, bombers and even Air Force One, and the Trump speech.“People are coming from far and wide to join us today and tonight for what is turning out to be one of the biggest celebrations in the history of our country,” Trump tweeted Thursday morning, which he was spending at a golf course just outside Washington. “I will speak on behalf of our great Country!”Trump has promised the “show of a lifetime,” but it may not go entirely the president’s way. A flash-flood watch alert was issued and some aides privately fear crowds won’t meet the president’s expectations -- evoking his 2017 inauguration.Protesters have a permit to display an inflatable version of the president that depicts him as a baby in a diaper with small hands. A similar blimp has greeted Trump on trips to London, but the Washington version won’t be allowed to leave the ground.Rebranded CelebrationGates open at 3 p.m. for his event -- six hours before fireworks begin -- with temperatures already at 90 degrees Fahrenheit (32 degrees Celsius) at midday, though forecast to dip slightly later.Trump is effectively rebranding a celebration that attracts thousands of families to watch the fireworks but almost never includes presidential speeches on the Mall. Critics say his revisions risk turning Washington’s July 4th into a de-facto Trump rally that’s likely to draw counter-protests.Delegate Eleanor Holmes Norton, a Democrat who represents the District of Columbia in Congress, said Trump’s plans “look like a political event” and predicted a light turnout for his speech.“I think the president is in for another flop, and he’s going to have to explain a flop that he set up,” Norton said. “He’s still smarting from the thin crowds at his inauguration. All I can say is: You ain’t seen nothing yet.”The White House rejected the idea that the celebration would be political. Trump told reporters on Monday that the event will be “about this country and it’s a salute to America.” He said he hoped for a large turnout. Asked if he could give a speech to all Americans, Trump replied: “I think so, I think I’ve reached most Americans.” He went on to criticize Democrats on health care and taxes.Military ParadeTrump conceived the event after his plans for a military parade on Veterans Day were stymied by complaints from local officials about the cost. The president has been enamored of the idea of a Washington celebration with a military component since attending the 2017 Bastille Day parade in Paris, which included an aerial display, thousands of marching soldiers and hundreds of military vehicles.Trump’s remarks are expected to last roughly half an hour, an administration official said, speaking on condition of anonymity. His speech will celebrate America’s independence, the flag and the military, the official added.Trump will reserve space for special guests -- the Trump campaign and Republican National Committee have received tickets, while the Department of Defense, with 5,000 tickets of its own, will send several top officials, including Acting Defense Secretary Mark Esper.Federal law bars political fundraising in government buildings or rooms where officials perform their duties, but doesn’t restrict presidents from inviting deep-pocketed donors to the White House or official events.The fireworks generally last about 15 minutes but this year will span 35 minutes after a donation by two pyrotechnic companies valued at $750,000. Because of the flyovers, the Federal Aviation Administration will suspend commercial air traffic at Reagan National Airport near Washington for the first time during a July 4th celebration. The FAA said flights would be affected again during the fireworks display.Abrams TanksThe Defense Department said Tuesday that it would provide a pair of M1A2 Abrams tanks and two M2 Bradley Fighting Vehicles for the event. They were delivered on flatbed trucks ahead of Thursday’s event, to avoid damaging streets.There will be several flyovers, including by the Navy’s Blue Angels flight team. The air show will also include Air Force One, a Marine One presidential helicopter, two F-35 fighter jets, two F-22 Raptors, two F/A-18 Hornets, a B2 bomber and four Apache helicopters.The event also is renewing a long-simmering feud with local officials in Washington. The city has said it’s still owed about $7 million from costs associated with Trump’s inauguration but the administration official said the District hasn’t asked for funds from upcoming federal budgets.Trump said Wednesday on Twitter that the cost of the event “will be very little compared to what it is worth,” while the administration official earlier declined to say how bill would be covered. Norton said Trump is “doubling up, tripling up on what he owes the District of Columbia.”Presidential RemarksWhile some of Trump’s predecessors have spoken on or around July 4th, they haven’t done it in quite the same way.Barack Obama delivered annual Independence Day remarks from the White House. Ronald Reagan gave a “Star Spangled Salute to America” speech at the Jefferson Memorial, near the Lincoln Memorial, in 1987, but did so on the morning of July 3.Richard Nixon recorded an address that played at the July 4, 1970, celebrations, which were marked by protests over the Vietnam War. Harry S. Truman spoke at the Washington Monument on July 4, 1951, 175 years after the Continental Congress approved the Declaration of Independence.Not all presidents’ attempts to celebrate July 4 have gone smoothly. In 1845, President James K. Polk hosted fireworks at the White House. With thousands of people gathered to watch, some of the rockets were accidentally fired into the crowd. At least one person was killed.(Updates with flash-flood alert in fifth paragraph.)\--With assistance from Margaret Talev, Bill Allison and Tony Capaccio.To contact the reporters on this story: Josh Wingrove in Washington at jwingrove4@bloomberg.net;Jennifer Jacobs in Washington at jjacobs68@bloomberg.netTo contact the editors responsible for this story: Michael Shepard at mshepard7@bloomberg.net, Scott Lanman, Tony CzuczkaFor more articles like this, please visit us at bloomberg.com©2019 Bloomberg L.P.
