Jimmy Fallon regularly "slow-jams the news" with his house band, the Roots, on Late Night, but last night he did the bit with none other than Barack Obama. The president – or as Fallon calls him, the "Preezy of the United Steezy" – spoke out on the need to lower interest rates on student loans over a mellow R&B groove. It's a wonderfully silly bit, but also a surprisingly solid piece of political rhetoric.
