Coverage of the Saturday night Democratic debate has focused on Bernie Sanders’ apology to Hillary Clinton for his staff’s poor judgment in viewing her campaign’s proprietary data. But Clinton issued a “sorry’’ of her own — although for a far less serious matter.

Clinton apologized to a live television audience for returning late from the ladies’ room after the break.

Smith declined to comment for the story.
