The issue at hand started with the "Johnson Amendment," named after then-Sen. Lyndon Johnson's 1954 measure that prohibits nonprofit groups who maintain tax-exempt status, including churches and charities, from directly participating in politics.
But efforts to repeal the Johnson Amendment have resulted in language that would ease political speech rules for all nonprofits. The results, critics say, could effectively let people deduct de-facto political donations and further hide those donations and spending from the public.
"This is taxpayer-subsidized "Citizens United,'" said Ian Vandewalker of the Brennan Center for Justice, referring to the 2010 landmark Supreme Court case that loosened campaign finance rules.
The
House tax bill passed in November included a repeal of the Johnson Amendment, while the Senate did not. Currently, lawmakers are at work reconciling the two bills.
Opponents of the Johnson Amendment, including President Donald Trump and top evangelical leaders, say the law stifles religious freedom.
