Congress, not the White House, asked the IRS to subject organizations suspected of being PAC's seeking 501(c) tax exempt status to additional scrutiny. From what I've read the head of the IRS became aware of the problems in doing this in 2012 and addressed the matter to stop any abuses. The White House really has nothing to do with this issue that was fundamental internal to the IRS.
Why is it that when any jerk-off idiots in the government screw up that Republicans blame the President as if the President ordered them to do it? The President did not order the additional scrutiny of the 501(c) applications, Congress did, and any problems with implementing the wishes of Congress was internal to the IRS. The "fix" was already implemented by th IRS long before the President was even aware of any problem existing.
Historically the Dixiecrats were little more than a surrogate for the KKK and today, based upon the political rhetoric of Donald Trump, I have to ask if the current Republican Party is in danger of also becoming the political party of White Supremacist/White Nationalist hatred replacing the old Dixiecrats.
