Obama offered them "a hearty congratulations" and recapped the teams' exploits -- the Galaxy winning their second title in a row and fourth in franchise history and the Kings winning their first Stanley Cup despite a mid-season coaching change and narrowly making the playoffs.
But the president went on to say the two teams "are full of some pretty stand-up players and coaches" beyond the playing field and ice rink.
"They're out in the community year-round. They're changing lives. They're making a difference," Obama said.
"As Coach [Bruce] Arena of the Galaxy says, 'The soccer is very much secondary. If we can have an impact on the lives of young kids, we want to be a part of that.'
"And that's something we all appreciate, especially those of us who are parents. And we are thrilled that you guys are sticking around to host a Let's Move question-and-answer session with kids from all across the country."
The Galaxy and Kings both presented Obama with a jersey and the soccer team threw in a ball for good measure.
