Presidents Barack Obama and George H.W. Bush made a rare joint appearance today to honor Iowa farm couple Floyd Hammer and Kathy Hamilton, who received the 5,000th Daily Point of Light Award.

Hammer and Hamilton were honored for their non-profit, Outreach, which provides meals to hungry children in 16 countries, including the United States. Outreach’s work is focused in Tanzania, where local workers weave baskets that are exchanged for food packaged by volunteers.

Outreach’s U.S. operation is based in the farming town of Union, Iowa. There, local volunteers have played a large role in the organization’s success. Today during the awards ceremony, Hamilton noted that Outreach has packaged and distributed 236 million meals to needy children since the group’s founding.
