Isn't making the sign of the cross a catholic thing? The President is not Catholic.
It's not exclusively Catholic. Lutherans and some other denominations do it. Traditionally it is done with the right hand, but insistence that there's something wrong with doing it lefty is just superstition.
The President isn't Lutheran either, he's Protestant so how likely is he to know about another religion's idiosyncrasies? Not everyone knows about their left hand hangup.
