Donald Trump is laying mattresses for the release of his tax returns. His periodically besieged and perpetually angry campaign manager, Corey Lewandowski, told CBS News that the presumptive Republican nominee for president will provide his returns as soon as the Internal Revenue Service concludes an audit.

As another episode in the reality series that has become the presidential campaign, the interview is worth watching. It exemplifies the Trump approach: Confuse the issue, pivot from defense to offense and identify a new villain or two. As the questions get tougher, allow the natural bully to escape just long enough to intimidate serious inquirers while invigorating core supporters who embrace anger.
