Why does the left disapprove of this? Maybe because the left is down on capitalism to begin with. No complaints from the left when Obama gives the Muslims, including the terror group known as the Muslim Brotherhood, billions in aid and tons of tanks, weapons and planes. You guys don't mind Obama handing over these things to terrorists at the expense of tax payers, but you have a problem with Trump earning money by doing business?
At least Trump doesn't hand the extremists anything they want and then excuse them when they attack.
