PORTLAND, Ore. – Police said Wednesday they are reopening an investigation into a Portland massage therapist’s allegations that former Vice President Al Gore groped her at an upscale hotel in 2006.

In a brief statement, the Portland Police Bureau did not say why it was reopening the investigation. Police earlier said they considered the case closed because there was no evidence.

A spokeswoman for Gore said the former vice president “unequivocally and emphatically” denied making unwanted sexual advances toward the woman and welcomed the investigation.

The masseuse alleges Gore made unwanted sexual advances during a massage appointment on Oct. 24, 2006, at the downtown Hotel Lucia, where Gore was reportedly registered as “Mr. Stone.”
