Footage has emerged of a protester being ejected from a Donald Trump rally in Pennsylvania, as the president taunts security.<br /><br />The president's comments at the Keep America Great Rally in Hershey, where he taunted security for not roughing up the protester, later drew criticism.<br /><br />The woman was wearing a T-shirt with a pink outline of a hand with a raised middle-finger and the words "grabbing power back", in an apparent reference to comments made by Trump about grabbing women by the genitals.<br /><br />During the rally he returned to familiar themes: accusing "Obama's FBI" of being behind a witch hunt against him, and lashing out at critics.<br /><br />The mood was not entirely negative however, with people in the crowd dancing along to the Village People hit 'YMCA', widely considered a gay anthem.
