WASHINGTON (AP) — President Barack Obama says he felt humbled after he and the Rev. Billy Graham prayed for each other.

Speaking at the National Prayer Breakfast, Obama recalled his visit to the evangelist's North Carolina home in 2010.

The president said that when Billy Graham prayed for him, he felt led to respond in kind, and prayed from the heart.

The 93-year-old Graham sent a message that was read at this morning's prayer breakfast regretting his inability to attend, and commending what he called "the foundation of unity you embody around the person of Jesus."
