JOPLIN, Mo. - President Barack Obama toured the devastation in Joplin, Mo. today, a week after a tornado tore through the small Midwestern town.

The tornado killed more than 120 people and injured hundreds. Joplin officials say at least 40 people remain unaccounted for.

At a memorial service Sunday, Obama pledged government support to help the community rebuild.

Helping in the recovery effort are Long Island volunteers such as Jeff O'Neil, from Huntington, who has been in Joplin for a week to provide assistance to the ravaged town.

Officials from the Red Cross say that they have adequate supplies to help the victims of the tornado, but are asking for monetary donations to help aid in the recovery.
