With the house v****g on holding Barr in contempt, it would appear he prefers they not go there, probably because a likely next step would be to impeach him.

Mnuchin on the other hand may be toast, not only does he have zero legal standing to prevent the IRS from turning over Trump tax returns, the Washington Post published a leaked document from the IRS legal department that told Mnuchin he had no choice. Their little caveat "unless the president asserts executive privilege" meant nothing as there would be no possible grounds for that.

It would make perfect sense to impeach Mnuchin for violating a house subpoena.

Cleaning the swamp, one dirty slime at a time.
