 The US Secret Service said it had detained the driver of a rented box truck that crashed into security barriers near the White House on Monday night, perhaps intentionally, but that there were no injuries or ongoing danger. A Reuters witness said investigators found a Nazi swastika flag that apparently came from inside the truck, which crashed into barriers at Lafayette Square, adjacent to the White House grounds. Officers retrieved the flag and plastic evidence bags that had been laid out on the sidewalk, following the crash and placed them in the back of the U-Haul, or Reuters photographer said. The exact location of President Joe Biden at the time was unclear. He met with Speaker of the US House of Representatives Kevin McCarthy at the White House earlier on Monday evening.
