Looks like Al Gore really will have to think twice before he gets any more massages.

Portland, Ore., detectives interviewed the former vice president a week ago in San Francisco regarding an alleged incident with licensed massage therapist Molly Hagerty, according to Portland television station KATU.

Hagerty claims the environmental enthusiast demanded sexual favors from her and also made "unwanted sexual contact" during a massage in a Portland hotel room in 2006.

The Portland Police Bureau decided to reopen the sexual assault investigation about a month ago. Hagerty went public to the National Enquirer in June and held up a pair of "soiled" pants from the alleged incident for the tabloid's cover.

Police questioned Gore the same day the Enquirer published stories of two other massage therapists who claimed Gore also made unwanted sexual advances toward them.
