Protests objecting to the July 4 Washington, D.C. celebration, "Salute to America," led to flag burning, arrests, and protesters chanting: "Imagine a world without America."
Videos on Twitter showed the U.S. flag burning outside the White House and Revolution Club activists chanting anti-America propaganda.
Revolution Club's Gregory Johnson and two associates were arrested by the Secret Service, according to the Washington Examiner.
The demonstration, marching toward the White House on Pennsylvania Avenue from the Treasury building, featured a fight of more than a dozen people around 5 p.m. ET, according to The New York Times.
A Secret Service agent was burned grabbing the flag, then another used a fire extinguisher to put it out, per the report.
