Usually people exaggerate when a more considered use of facts makes less of an impact. In this case, it seems unneeded. He could have just said, "Hillary was the Secretary of State and presumably was trained on how to deal with classified information and yet apparently did not and thus is unqualified to be President." And then someone else could say, "Trump's refusal to listen to intelligence briefings on Russia means that he is unqualified to be President". And then we'd have no candidates! Oh, except for Stein and Aleppo guy.
