Erik Prince, founder of the now-defunct private mercenary firm Blackwater, is preparing a challenge against Wyoming Republican Senator John Barrasso in next year’s primary election. Prince was reportedly urged to run by Steve Bannon, Donald Trump’s former chief strategist and editor of the far-right news site Breitbart. Prince has financial support from New York hedge fund manager and billionaire Robert Mercer and his daughter Rebekah, who are heavily invested in Breitbart and funded Donald Trump’s campaign. Prince recently made headlines when the White House indicated it was considering his plan to appoint a U.S. “viceroy” in Afghanistan while privatizing much of the war effort.
