 As clouds swirled over dress rehearsal for PBS’s “A Capitol Fourth” on Sunday morning on the West Lawn of the U.S. Capitol, host Tom Bergeron couldn’t help but throw in a few jokes about the weather as he practiced his lines via teleprompter. Fake footage of fireworks on the Fourth???? — Chris Wallgren (@seawall77) July 5, 2016 
 
 PBS representatives didn't immediately return NBC News' calls for comment Monday night. [D.C.-area forecast: Rain likely for the Fourth, but not necessarily a total washout all day and evening]

 “Oh, no,” he told us backstage. ET, the show's Facebook and Twitter pages acknowledged that the supposedly "live" show was, in fact, " a combination of the best fireworks from this year and previous years."
– Noticed something a bit off about PBS' A Capitol Fourth broadcast Monday? So did hundreds of people who took to Facebook and Twitter, per NBC News. Though host Tom Bergeron initially laughed off concerns that the live concert and fireworks display over Washington would be rained out, per the Washington Post, the sky above the Capitol Building was foggy and overcast as the fireworks began. That made seeing the show a bit difficult—so PBS intervened. Mingled with misty footage of fireworks over the Capitol building, with scaffolding clearly visible, was stock footage of fireworks from previous celebrations. Viewers were quick to call out the "fraudulent" scheme—there was no disclaimer during the "live" broadcast—noting the stock footage showed a clear sky over the Capitol Building, and no scaffolding, per the Post. Afterward, the show admitted to showing "a combination of the best fireworks from this year and previous years" because of the poor conditions. "It was the patriotic thing to do," reads a tweet from the Capitol Fourth account. "We apologize for any confusion this may have caused." The apology didn't appease some, though. "How is using stock video patriotic?" one user wrote. "If I wanted that, I'd watch YouTube." (A Texas teen tried to make a "fireworks bomb" and paid a steep price.)
