A man drove his car into a barricade near the U.S. Capitol early Sunday and then began firing gunshots in the air from the burning car before fatally shooting himself, police said.
The incident happened just before 4 a.m. at a vehicle barricade set at East Capitol Street and 2nd Street in Washington.
It comes at a time when law enforcement authorities across the country are facing an increasing number of threats and federal officials have warned about the potential of violent attacks on government buildings in the days since the FBI's search of former President Donald Trump's Mar-a-Lago estate in Florida.
