America's top elected leader and its most powerful banker are fighting over who is smarter.

Really.

President Donald Trump early Thursday scoffed at JPMorgan Chase CEO Jamie Dimon's claim that he could "beat" Trump and is just as tough and smarter than the 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."
