Donald Trump has disavowed the so-called alt-right, a movement of right-wing activists often linked to white nationalism, after a rally on Saturday in which members gave Nazi salutes and shouted "Hail Trump".

He told the New York Times that he did not understand why such groups had been drawn to him.

He also announced that he will not seek to pursue a criminal investigation against Hillary Clinton over her email scandal and charitable foundation, and wants to help her "heal" following their brutal election battle.
