Donald Trump has rescinded his pledge to support the Republican nominee for president. "We'll see who it is," he said Tuesday during a CNN town hall. He said he had been treated "unfairly" by the Republican National Committee and the GOP establishment. He said he was unsure whether the Republican establishment was plotting to take the nomination away from him during the convention in Cleveland. He also said he didn't need Cruz to promise to support him should Trump win the nomination. "I’m not asking for his support," Trump said.
