Story highlights Clapper emphasized he was speaking as a private citizen.

Clapper questions Trump’s “Fitness” to hold the presidency following Trump’s divisive campaign rally in Arizona.

“What caused concern is this … Jekyll-Hyde business w he’ll make a scripted teleprompter speech, which is good, and then turn around and negate it by sort of, unbridled, unleashed, unchaperoned Trump. And that to me – that pattern – is very disturbing,” Clapper told Jim Sciutto in an interview on CNN’s “Erin Burnett OutFront.”

Clapper emphasized he was speaking as a private citizen and not as a member of the intelligence community.

Clapper – a CNN national security analyst – had questioned Trump’s “Fitness” to hold the office of the President less than 24 hours earlier.

“I really question his ability to be – his fitness to be – in this office, and I also am beginning to wonder about his motivation for it,” Clapper told CNN’s Don Lemon on Wednesday morning after the rally had ended.

On Monday, Trump portrayed a more polished version of himself as he announced the United States’ new strategy for Afghanistan.

Wednesday, Trump was more reserved in a speech at the American Legion in Reno, Nevada, w he called for healing and unity.
