"I was never a fan of Colin Powell after his weak understanding of weapons of mass destruction in Iraq = disaster. We can do much better!" Trump wrote on Twitter.
In one email, the former secretary of state called Trump a "national disgrace" and "international pariah" — adding that the GOP presidential contender was "in the process of destroying himself, no need for Dems to attack him."
