A simple interview with MSNBC’s “Morning Joe” turned into a Sarah Palin moment, when Libertarian candidate for president Gary Johnson was asked about Aleppo while talking about Syria and ISIS.

“And what do you do about Aleppo?” Mike Barnicle asked Johnson.

“And what is Aleppo?” Johnson asked. Barnicle asked if he was kidding.

Aleppo, of course, is the part of Syria we see splashed across the news for chlorine attacks and refugee camps. It’s a major part of the conversation about how we handle the war against ISIS.

It didn’t take long before Twitter was lighting up with #WhatIsAleppo and calling the statement career ending or disqualifying for a presidential candidate. “Morning Joe” panelist Mark Halperin remarked that Johnson and other third party candidates pitch that they should be taken seriously, but how can they be when they don’t know basic information about foreign policy.

Check out the Twitter backlash below (and a video of the face-plant):

.@mikebarnicle: What would you do, if you were elected, about Aleppo? @GovGaryJohnson: And what is Aleppo? https://t.co/ZbqO5RAEsk

"A three word sentence meaning, 'end of campaign'".

Johnson: "what is Aleppo?"

Trebek, sighing: "that is correct, Gary"

@GovGaryJohnson EPIC FAILURE! You lost my advocacy to hear anymore from you. You killed a movement… 😔 #Aleppo

Poor journalism is a man running for commander-in-chief admitting on live TV #whatisAleppo & the journos letting him respond casually anyway

You COULD view @Morning_Joe #WhatIsAleppo moment as an implicit critique of Lauer's questions at last night's forum https://t.co/fYLmEuioY9
