Speaking from the White House, Obama stressed that "Oklahoma needs to get help right away in wake of devastating tornado."

Obama calls the devastation that tore through the Oklahoma City suburbs, quote, "one of the most destructive tornados in history," even though he said the extent of the damage is still unknown.

"One of the most destructive tornadoes in history sliced through the towns of Newcastle and Moore, Oklahoma. In an instant, neighborhoods were destroyed, dozens of people list their lives, many more were injured, and among the victims were children, trying to stake shelter in" the safest place they knew, their school, Obama said

Obama spoke Tuesday after an Oval Office briefing on the latest developments from his disaster response team and as Federal Emergency Management Agency Director Craig Fugate was heading to Oklahoma.

Obama spoke following a meeting with his disaster response team, including Homeland Security Secretary Janet Napolitano and top White House officials. On Monday, he spoke with Oklahoma Gov. Mary Fallin and Republican Rep. Tom Cole, whose home is in the heavily damaged town of Moore, a suburb of Oklahoma City.

Obama has declared a major disaster in Oklahoma, ordering federal aid to supplement state and local recovery efforts.

He also recognized the efforts of those who helped protect children and rescue victims in the hours since the tornado. "Our gratitude is with teachers who gave their all to shield their children; with the neighbors, first responders and emergency personnel who raced to help as soon as the tornado passed and with all of those who, as darkness fell, searched for survivors through the night."

The president offered prayers and said there's a long road of recovery ahead.
