Clinton Campaign HQ Evacuated
Staff working at Hillary Clinton's campaign headquarters in Brooklyn were forced to evacuate the building following the discovery of a white substance in an envelope.
Police say two interns working for the US presidential candidate made the discovery in her Manhattan office, before bringing it forward to the Brooklyn office.
Four people were exposed to the substance, which is being tested, but there are no reports of any injuries or illness.
At this stage it's not known what the substance is.
Clinton was not in New York at the time of the evacuation.
