A series of massive storms swept the South, triggering an onslaught of dozens of tornadoes late Wednesday. Nearly 300 people have been killed across six states as a result of the storms.
From the AP:
After witnessing the damage in storm-wracked neighborhoods, Obama said he's "never seen devastation like this."
He promised residents: "We're going to make sure you're not forgotten."
