Trump threw the barb at Carson, a retired neurosurgeon at the prestigious Johns Hopkins Hospital who was the first to separate twins conjoined at the back of the head, Thursday on CNN's "New Day."
Morton Klein, the president of the right-wing Zionist Organization of America (ZOA), asked TPM about Trump's slight on Carson's medical prowess during a Thursday phone interview. After he was told Trump called Carson just an "okay doctor," Klein said the remark showed the real estate mogul may be a little too hot-headed for the Oval Office.
“Trump is making many of us very nervous,” Klein said. “He doesn’t have the temperament to be president. I mean really, to lash out at Carson as a talented doctor? You don’t know what you’re talking about.”
Klein is an ally of Sheldon Adelson, the Las Vegas casino magnate and big-time GOP donor who has yet to back a particular candidate in the 2016 race. Trump headlined the Iran deal protest rally, which ZOA co-sponsored, alongside Sen. Ted Cruz (R-TX). Carson did not attend.
