Obama: Americans stand with Oklahoma for 'as long as it takes'

Describing the tornado that swept across Oklahoma plains as "one of the most destructive storms in history," President Barack Obama said Tuesday the state "needs to get everything it needs right away" to recover from the devastating twister.

The president, speaking from the State Dining Room at the White House, said he doesn't yet know the "full extent" of the damage or the "human and economic losses that may have occurred."
