U.S. President Barack Obama has made no secret of his contempt for Donald Trump.
But he reserved some of his sharpest words for the Republican contender for a press conference at a Nuclear Security Summit on Friday.
Obama shaded Trump for his knowledge of nuclear weapons, foreign policy and, basically, the world.

Obama was responding to comments that Trump has made about nuclear weapons in a number of forums.
One of them was a 100-minute-long interview with The New York Times, in which he he said he wouldn't mind letting South Korea and Japan develop their own nuclear weapons to defend themselves against China and North Korea, instead of having Americans protect them.
Trump made similar remarks in a CNN town hall this week.
"You have so many countries already — China, Pakistan, you have so many countries, Russia — you have so many countries right now that have them," he said.
"Now, wouldn't you rather, in a certain sense, have Japan have nuclear weapons when North Korea has nuclear weapons?"
But such a plan has been derided by leaders of both Japan and South Korea, MSNBC reported.
Japanese Foreign Minister Fumio Kishida said, "It is impossible that Japan will arm itself with nuclear weapons."
And in addressing Trump's remarks, Obama went on to say, "We don't want someone in the Oval Office who doesn't recognize" the importance of America's "nuclear security in Asia," according to MSNBC correspondent Ari Melber.

This is hardly the first time that Obama has weighed in on the upcoming U.S. presidential election, though he has mostly stayed out of it.
In February, he said he continues "to believe Mr. Trump will not be president," CNN reported.
"And the reason is that I have a lot of faith in the American people. Being president is a serious job. It's not hosting a talk show, or a reality show," he added.
