The Washington Post reports:
Ben Carson, the neurosurgeon turned presidential candidate turned unfiltered pitchman for Donald Trump and now part of the presumptive nominee’s vice presidential search committee, sat in the back of a Town Car with his wife, Candy, on his way to a televised interview. He had just explained to the reporter riding along that he wanted no role in a Trump administration when news arrived of a new poll naming him as the best-liked of a list of potential running mates.
“Who else was on the list?” he asked quietly, maintaining his usual inscrutable calm. The most favorably regarded contenders after himself, he was told, were John Kasich, Marco Rubio, Ted Cruz, Sarah Palin and Chris Christie. “Those are all people on our list,” he said. “Well, not you,” Candy reminded him sharply. That the Trump campaign might want its potential VP picks held close to the vest didn’t seem to occur to Carson. He’s not the type to keep his candid thoughts to himself.
In an update to the above-linked story, the Post notes that Carson later tried to walk back the revelation.
