Did President Barack Obama have such a moment this week when he wept openly about children killed by gun violence?
Some say yes, and that Obama's tears were more radical than people realize. Most people know the backdrop: While announcing executive orders Tuesday to strengthen gun control laws, Obama halted as the cameras clicked. He tried to regain his composure, but then the tears flowed as he talked about 20 schoolchildren murdered by a gunman at Sandy Hook Elementary School in 2012.
Some commentators later said the moment was remarkable because Obama is known for his apparent Spock-like emotional detachment.
