LAKE FOREST, Calif. — Pastor Rick Warren is set to deliver the invocation for President-elect Barack Obama's inaugural swearing-in ceremony on Jan. 20, Saddleback Church officials confirmed Wednesday. Kristin Cole, a spokeswoman for Warren, said church officials were waiting on Obama's team to make the announcement. Just this past August, Obama and John McCain were guests at the two-hour Saddleback Church Civil Forum on Leadership and Compassion where Warren questioned them about issues that ranged from abortion and same-sex marriage to the nature of good and evil.
