Whoops: it looks like neurosurgeon-turned-politician Ben Carson has made another gaffe as part of presumptive GOP presidential candidate Donald Trump’s staff.

On the way to a televised interview, Carson, chief of Trump’s vice presidential search, revealed several names on Trump’s shortlist for a running mate — while a reporter was nearby, according to an article posted Sunday on the Washington Post. Listening to someone tell him the results of a new poll on the best-liked vice presidential candidate, Carson confirmed some well-known names that could be on the ticket: Sarah Palin, Ted Cruz, Carson himself, Marco Rubio, John Kasich and Chris Christie.

“Those are all people on our list,” Carson reportedly said.

Carson’s wife, Candy, reminded him that he, in fact, isn’t on the list.

Palin may be the buzziest name on the list. She previously ran as a vice presidential candidate on John McCain’s 2008 ticket. She later retired as the governor of Alaska.

This isn’t the first slip-up Carson’s made since joining Trump’s staff. He previously told a reporter that even if Trump was a bad president, it would only last for four years, and that he was only supporting the controversial candidate to be “pragmatic.” As the Post’s article pointed out, Carson isn’t the type to keep his thoughts to himself.
