Trump isn't a businessperson, he has failed early & often: Cuban

'Shark Tank' star Mark Cuban said US presidential nominee Donald Trump isn't a great businessman, while Kamala Harris is pro-business contender. Cuban was asked if he'd invest in Trump's campaign if he came on 'Shark Tank', listing Trump's ventures of selling Trump-branded shoes, coins and bibles. The billionaire said, "No, he's desperate…He's not a businessperson…He has failed early and often."
