From W’s former chief of staff, Andy Card:
I found that Ronald Reagan and both President Bushes treated the Oval Office with tremendous respect. They treated the Office of the Presidency with tremendous respect. And some of that respect was reflected in how they expected people to behave, how they expected them to dress when they walked into the symbol of freedom for the world, the Oval Office. And yes, I’m disappointed to see the casual, laissez faire, short sleeves, no shirt and tie, no jacket, kind of locker room experience that seems to be taking place in this White House and the Oval Office.
Because that’s what really matters. You need to be well dressed while you’re destroying the separation of powers, suspending habeas corpus, spying on American citizens and authorizing torture.
