Donald Trump whacked Hillary Clinton as unfit to be president, citing her mishandling of email as secretary of state, while addressing cybersecurity on Monday.

“Hillary Clinton’s only experience in cybersecurity involves her criminal scheme to violate federal law, engineering a massive coverup and putting the entire nation in harm’s way,” Trump said.

“The fact that a former senator and secretary of state claimed not to know what the letter ‘C’ means is just one more example of why she’s unfit to hold public office.”

Trump said cyber-breaches are one of our most critical national security concerns. He called for the creation of a “cyber review team” to spot weaknesses in the face of mounting hack attacks from foreign countries.
