Trump reiterated the false claim he has made about Clinton during his transition to a general election campaign that "Hillary Clinton wants to abolish the Second Amendment," a statement that has been deemed "false" by Politifact.
He also called her the worst secretary of State in history and said anybody else embroiled in her current email scandal would be in prison.
"Honestly, she should not be allowed to run. It's a disgrace to the laws of our country," Trump said, referring to the FBI's investigation into Clinton's use of a private email server while secretary of State.
