Republican presidential candidate Jeb Bush is catching flak on Twitter after posting an image of a gun with just one word to go along with it — "America."

The former Florida governor did not explain why he posted the photo of the gun, which has "Gov. Jeb Bush" engraved on it, and the social media response was swift.

I know your campaign has not worked out so far, @JebBush, but you have a lot to live for. https://t.co/QvWhxxtFXc — Jonathan Chait (@jonathanchait) February 16, 2016
