CNN keeps predicting Trump will die of a heart attack, which brings to mind the CIA poison dart gun that can trigger one.

Revealed by the Church Committee in 1975, the "heart attack gun" is a modified 1911 that can shoot a dart with a deadly poison that's nearly undetectable – which is perfect for political assassinations.

"The poison was frozen into some sort of dart and then it was shot at very high speed into the person," saidCIA whistleblower Mary Embree. "When it reached the person it would melt inside them, and there would be a tiny red dot on their body, which was hard to detect."

"There wouldn't be a needle or anything like that left in the person."
