Some took to social media to blast PBS for showing old footage during the live broadcast. They pointed out other tell-tale signs that the video wasn't live, such as the shots of the U.S. Capitol's dome without a scaffolding. The dome is currently undergoing a restoration project.
"A Capitol Fourth" tweeted an apology and said: "We showed a combination of the best fireworks from this year and previous years. It was the patriotic thing to do."
