Officials launch murder probe into death of officer following DC protests

A video still from the so-called

Brian David Sicknick, 42, died Thursday of injuries he sustained while trying to protect the Capitol from a mob of violent rioters supporting President Donald Trump who rushed the building to disrupt the certification of the presidential election. He was tweeting again after his Twitter account was reinstated, reverting to an aggressive statement that his supporters must not be "disrespected" after he sent out a calmer Thursday video decrying the violence.

His social media pages suggest that he was a supporter of Mr Trump. It's a highly unusual defense to criticism that hasn't previously warranted an riposte from America's top diplomat.
