A former head of the Defense Intelligence Agency says Hillary Clinton shouldn't be campaigning as long as her emails are under investigation.
A former Obama administration intelligence official says Hillary Clinton should stop campaigning.
Retired Lt. Gen. Michael Flynn told CNN that Clinton should halt her campaign until she's cleared by the FBI regarding her email server.
In the CNN interview, Flynn dismissed the argument that Clinton's emails have been overclassified, meaning some emails now considered classified weren't in the past.
"Overclassification or not — if it's classified, it's classified, and she knows better," Flynn told CNN.
Flynn has also advised Republican presidential candidate Donald Trump, but said he'd give expert advice to any candidate who asked for it.
He's been generous with his criticism in the past, too. He's called the Iraq war a "huge error" and has been critical of how President Obama has dealt with ISIS.
