An atheist organization is suing the Internal Revenue Service for failing to take action against churches that the group says have violated the tax code for nonprofits by engaging in politics.

The Freedom From Religion Foundation, a watchdog group based in Madison, Wis., filed a federal lawsuit this week that cited the Oct. 7 actions of 1,600 pastors who violated the tax code on “Pulpit Freedom Sunday” – a nationwide display of free speech. After weeks of silence from the IRS, the Freedom From Religion Foundation took the matter to court. …

“The tipping point would have been the braggadocio of [1,600] pastors claiming they endorsed from the pulpit. The number of complaints we’ve received has been escalating, and we have no explanation from the IRS. This is our way of finding out what is going on.”
