AP-GfK Poll: Email investigation has hurt Clinton's image

WASHINGTON (AP) - A new Associated Press-GfK poll finds that Hillary Clinton enters the summer damaged by perceptions that she violated the law by using a private email system while serving as secretary of state.

More than half of Americans think the presumptive Democratic presidential nominee broke the law in using a private email account and server at the State Department. The poll shows that nearly 4 in 10 think she did so intentionally.

Clinton has battled against perceptions that she is dishonest and purposely set up the private email server to avoid public scrutiny.

FBI Director James Comey said last week that Clinton's actions did not warrant prosecution, and the Justice Department declined to seek criminal charges. But Comey said Clinton was "extremely careless" in her handling of classified material.
