Secretary of Homeland Security Janet Napolitano was in Moore Wednesday to meet with Governor Mary Fallin and other state and local officials.
In a news release the secretary stated she wanted to "ensure first responders are receiving the assistance they need in on-going response and recovery efforts to the severe weather that impacted the region."
Meanwhile, the head of the Federal Emergency Management Agency says officials are "going neighborhood to neighborhood" to make sure Oklahoma gets the help it needs.
FEMA's Craig Fugate promised that his agency won't desert Oklahoma, saying "We don't leave here when the cameras leave. We stay here and get the job done."
Fugate says FEMA has enough money to assist the people of Moore who were caught in the path of destruction as the nearly 1.3-mile-wide twister struck Monday afternoon.
Fugate arrived in Moore on Tuesday.
