"One hopes, at least, that Trump will henceforth refrain from complaining that undocumented immigrants broke the law, seeing as he has just instructed his Treasury Department not to take action against pastors who still, technically, break a law which is still on the books."

The author needs to stop to stop playing lawyer and judge and stick to topics in which he ostensibly has some expertise.  In this country we still have a first amendment right to say virtually anything that we want (including pastors), so a pastor speaking from the pulpit about certain political matters, is not "breaking the law."  He merely (at least in theory) is risking the tax exempt status of his non-for-profit organization.  He is not forbidden from speaking under the threat of some criminal action.
