Donald Trump: Hillary Clinton's Private Email Use was 'criminal'

Donald Trump on Sunday pitched into the ongoing furore over Hillary Clinton’s use of a private email server while secretary of state, saying: “The fact is, what she has done is criminal.”
A department official said on Friday that investigators this week asked the Justice Department to look into a “potential compromise of classified information” surrounding the private email server.
On Saturday, in Iowa, Clinton told reporters she never knowingly sent or received classified information using her private server and did not know what messages were being cited by investigators.
