Obama, Biden: Overseas at the same time (for a few minutes)

Tuesday night brought an unusual situation: President Obama and Vice President Biden overseas at the same time.

But only for a few minutes.

Obama departed aboard Air Force One for Israel at around 8:10 p.m.

Biden, returning on Air Force Two from Rome and the installation of Pope Francis, touched down at Joint Base Andrews near Washington at 8:27 p.m.

However you slice it, it wasn't a constitutional crisis.

Obama remains chief executive and commander in chief regardless of where he is, in the air or on the ground.
