FOX's Rachel Sutherland reports:
Clinton's speech on foreign policy angered the presumptive Republican nominee, the Democrat said Trump has a thin skin and is wrong to suggest America isn't already great:
(Clinton) "I just don't think he understands how strong we are, and how strong the people of this country are."
Trump said Clinton's speech was not Presidential, he also attacked her on the investigation into her private email system from when she was Secretary of State:
(Trump) "Folks honestly, she's guilty as hell. She's guilty as hell."
