Donald Trump’s new convention manager accused Sen. Ted Cruz’s campaign of using “Gestapo tactics” after the senator’s organization swept Colorado’s delegates on Saturday, shutting out the real estate mogul and further increasing the chances of a contested nominating convention in Cleveland. “Well, he’s threatening, you go to these county conventions, and you see the tactics, Gestapo tactics, the scorched-earth tactics,” Paul Manafort said of Cruz in a Sunday interview on NBC’s “Meet the Press.” Manafort, who helped manage the 1976 Republican convention for former President Gerald Ford, added that the Trump campaign would be filing “several protests” because Cruz’s campaign wasn’t “playing by the rules.”
