The Johnson Amendment (1954) prohibits churches from endorsing or opposing political candidates, or lose tax-exempt status
The Johnson Amendment is named for then-Senator Lyndon B. Johnson. It applies to all 501(c)(3) non-profit organizations, including charitable foundations, universities and churches. Republicans have sought to repeal it, arguing that it restricts the free speech rights of churches and other religious groups.
During the National Prayer Breakfast on February 2, 2017, Trump said:
“Freedom of religion is a sacred right, but it is also a right under threat all around us. That is why 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.”
