Boos as anti-Trump protester interrupts the national anthem to yell ‘Leave Greenland alone’

An anti-Trump protester crudely interrupted a moving rendition of the US national anthem to yell, “Leave Greenland alone!” before an NBA game being played in the UK.

Actress Vanessa Williams was performing “The Star-Spangled Banner” to respectful silence ahead of the clash between the Memphis Grizzlies and Orlando Magic at London’s O2 Arena when the heckler — who sounded American — loudly shouted his protest.

It sparked a wave of boos, before others applauded — and at least one person was heard shouting “f–k off” as others continued interrupting the anthem.

Unfazed, Williams completed her rendition ahead of the game that saw the Grizzlies win 126-109.
