Exorcizing Hillary?

This nugget from the Karl Rove biography seems too weird to be true:

Soon after Rove moved into his new office in the West Wing, previously occupied by Hillary Clinton, he invited three top Catholic priests to conduct a ceremony to purge the room of evil spirits. "It was an actual liturgical ceremony," says participant Deal Hudson. "We sat at the table, we prayed. A priest said a series of prayers, including a blessing."

Deal Hudson, however, is not likely to make this up. Maybe it was just a blessing. Whatever, it's not exactly reassuring about what drives the Bush administration, is it?
