The leader of Houston's Windsor Village United Methodist Church said Obama's "character, confidence and courage" inspired him to support his bid for the Democratic presidential nomination, the Houston Chronicle reported Sunday.

"I have been in contact with the Obama campaign team," Caldwell said. "I will be making visits on his behalf."

The pastor did clarify that his support of the Illinois politician was based entirely on his personal beliefs and did not represent support from his United Methodist church.

Caldwell's spiritual relationship with the Republican president has included performing the benediction at both of Bush's inaugurations.

Caldwell told the Chronicle he had informed Bush of his decision to back Obama and that the president accepted his decision.
