Reagan always had a suit and tie on in the Oval Office. Clinton was the first to wear running warmups into the office. Obama had the nerve to put his feet up on our desk. It all boils down to respect for the Office of the President and ultimately, the American people.
Sadly, there are pics of George Bush with his feet up also. It’s pathetic, disrespectful, so disrespectful, for any president to do that.
