This is the May 22, 2017, FULL EPISODE of VICE News Tonight on HBO. Twitter shareholders voted on a novel idea–letting users own the company. We talked to some of them to find out what this means. We traveled to Iran to see how the nuclear deal has affected the lives of ordinary citizens. Plus, a look back at the follies of past U.S. presidents in brokering peace between Israel and Palestine. And, Ringling Bros and Barnum & Bailey ended its 146 year run but a relative of the group is keeping the American circus tradition alive.
