Obama congratulates Clinton on PR win

From NBC/NJ's Athena Jones
MITCHELL, SD -- At the beginning of a rally outside the corn palace, a local attraction here decorated with corn husks, Obama congratulated Clinton for her win in Puerto Rico today.

"I just got off the phone with Sen. Clinton. She's gonna win Puerto Rico and I wanted to congratulate her for that," he said, before going on to praise the New York senator, saying the party would be unified for the general election and that she would be "a great asset when we go into November to make sure that we defeat the Republicans, that I can promise you."
