Allan Lichtman: Presidential historian on the alleged assassination attempt on Donald Trump

There's growing debate about what the alleged assassination attempt on Donald Trump will do to a politically turbulent America. Trump was hit in the ear by a bullet after a shooter opened fire at a Republican rally in Pennsylvania. Presidential historian Allan Lichtman says the political violence may well have a silver lining, as it did after the shooting of Ronald Reagan in 1981. "Instead of seeking revenge or attacking his political opponents, he formed a campaign for gun control - and for a while, it brought the country together."
