A shirtless New Zealander who saw the Capitol Hill shooting unfold has found instant fame as the "Bro Witness".
Matthew Jacobs, 26, followed the shooting drama on his rented bike after seeing a black sports car trying to ram through a temporary barricade at the White House.
He was mobbed by reporters, many of whom tweeted about his no-shirt and Miami dolphins cap ensemble.
National Journal journalist Matt Vasilogambros quickly dubbed him "Bro Witness".
