President Trump said Thursday that JPMorgan CEO Jamie Dimon would not be a good president because he is a “nervous mess” who doesn’t have the “aptitude” or “smarts” to be president.

“The problem with banker Jamie Dimon running for President is that he doesn’t have the aptitude or ‘smarts’ & is a poor public speaker & nervous mess – otherwise he is wonderful,” Trump tweeted. “I’ve made a lot of bankers, and others, look much smarter than they are with my great economic policy!”
