DJ Snake and Lil Jon have some serious competition from Michelle Obama ...and a turnip?! On Tuesday, the White House posted a 6-second Vine of the first lady dancing — root vegetable in hand — to the tune of "Turn Down for What." Without missing a beat (or a beet!), Mrs. Obama says to the camera, "Turnip for what?" Mrs. Obama, whose Let's Move! program seeks to end the epidemic of childhood obesity, couldn't resist a chance to promote exercise and healthy eating on social media, so she responded with a Vine of her own!
