WASHINGTON (AP) — The Rev. Joseph Lowery has thanked God for letting Barack Obama inspire the nation to believe that "yes, we can" work together toward a "more perfect union."

Delivering a benediction at the end of Obama's inauguration ceremony, Lowery said Obama takes office at a "low moment" in the nation's and the world's economic health. He prayed for an end to "exploitation" of the weak and poor, and what he called "favoritism toward the rich."

The 87-year-old Methodist is considered the dean of the civil rights movement, helping lead the Montgomery bus boycotts in the 1950s and delivering a list of demands to Alabama Gov. George Wallace during the bloody Selma-Montgomery March in 1965.

After being asked to deliver the benediction at Obama's inauguration, Lowery said he's long hoped that an African-American would one day become president but didn't think he'd live long enough to see it.
