President Donald Trump retweeted a doctored video Sunday showing him knocking down Hillary Clinton with a golf ball, prompting another round of head-shaking and outrage from critics.

The GIF, which combines clips of Trump hitting a golf ball with Clinton stumbling on a plane — which happened in 2011, when she was secretary of state — had been posted by a vocal Trump supporter with a vulgar Twitter handle and a history of posting angry, disparaging rhetoric toward minorities.
