Mark Cuban Offers $10M to Charity if Trump Can Explain His 'Jibberish' Economic Plan

Billionaire businessman Mark Cuban bashed Republican nominee Donald Trump's economic plan today, unleashing a series of tweets at his former friend questioning the 2016 hopeful's intellect.

At a speech yesterday to the Economic Club of New York, the candidate — and billionaire businessman in his own right — promised to eliminate taxes for low-income Americans while growing the U.S. economy. The barrage of tweets by Cuban today was prompted by a television appearance in which Trump said Cuban is "not smart enough" to understand his economic plans.

Cuban fired back on Twitter, mocking the hotel magnate for supposedly not getting into the Ivy League University of Pennsylvania.

Cuban then pledged to give $10 million to the charity of Trump's choice if he would agree to an abnormally long interview on his economic platform.

Cuban then offered to write Trump a check and let him keep it, and added a taunt: "In the inmortal (sic) words of YOU. 'What do you have to lose ?'"
