Declaring that religious freedom is “under threat,” President Donald Trump vowed Thursday to repeal a rarely enforced IRS rule that says pastors who endorse candidates from the pulpit risk losing their tax-exempt status. “I will get rid of and totally destroy the Johnson Amendment and allow our representatives of faith to speak freely and without fear of retribution,” Trump said during remarks at the National Prayer Breakfast, a high-profile event bringing together faith leaders, politicians and dignitaries.
