D.C.'s July 4th fireworks will have "TSA-style" security, won't start until late

This year's Fourth of July celebrations in Washington, D.C. — marking the nation's 250th birthday — will include hours of military flyovers and a massive fireworks display that could stretch late into the night, with some of the tightest security in decades, officials said Monday. This Fourth will include "the largest display of fireworks our city has ever seen," D.C. Metropolitan Police Department Interim Chief Jeff Carroll said at a news conference. Usually the fireworks begin at around 9 p.m., but this year, they are expected to begin at 11 p.m. and are "going to be longer than in previous years, we are told," Mayor Muriel Bowser told reporters. President Trump has said he plans to speak at 9 p.m., ahead of the fireworks. Starting at 1:15 p.m., hundreds of planes will participate in a "Fourth of July Airshow," the president said. The National Mall also is hosting a daily event called the Great American State Fair that will run until July 10, and some local neighborhoods are hosting parades and other events on the Fourth. The main festivities have been deemed a National Special Security Event, a designation used for massive events like Super Bowls and presidential inaugurations. Security measures will be more extensive than for any Fourth of July event in D.C. since shortly after the 9/11 attacks, Carroll said, with more blocking vehicles, more fencing, concrete barriers and other security measures that aren't employed for a typical Fourth of July celebration. …
