The short video was filled with ominous music. It began by showing an Islamic State militant holding a knife, then cut to a photo of President Obama smiling while sitting in a golf cart.
From there, it moved on to video showing the US consulate in Benghazi, Libya burning following a terror attack in 2012. Then it cut to a video of Clinton dancing with her husband, former President Bill Clinton, at what appears to be a New Year's Eve celebration.
The Instagram video ended with text that read: "Politicians are having fun on our dime while the world is burning," followed by Trump's campaign logo and slogan.
Trump, whose financial disclosures showed he owns at least 15 golf clubs which generate about $190 million in revenue, posted a message on Instagram alongside the video that said simply: "Not under my watch."
