from www.nydailynews.com – Police have reopened an investigation into allegations that former Vice President Al Gore groped a masseuse in his Oregon hotel room four years ago.

Portland authorities announced Wednesday they were taking another look at the claims of Molly Hagerty after she outed herself as the do-gooder’s accuser.

Hagerty said she may have some inconvenient evidence stashed in a safe-deposit box – a pair of stained black pants and what’s left of a chocolate bar that she says Gore munched on.

Gore spokeswoman Kalee Kreider said her boss “unequivocally and emphatically denied this accusation when he first learned of its existence three years ago. He stands by that denial.” She added, “Further investigation into this matter will only benefit Mr. Gore.”

The Portland Police Bureau, which had considered the case closed because there was no evidence, did not say why it was reopening the investigation.

Of the possibly damning pants, Hagerty said, “I thought the stain could have occurred when Mr. Gore leaned on me while he was wearing an open robe.”

She said she already has had a $35 forensic test run on the pants that was inconclusive. She’s ready to turn them over for more extensive testing.

“Al Gore is a pervert and sexual predator,” the 54-year-old redhead told the National Enquirer.

Gore, who won a Nobel prize for sounding the alarm about global warming, has not been charged with a crime.

He is still dealing with the fallout from the fracturing of his 40-year marriage to high school sweetheart Tipper.

Hagerty, who lives in Portland, Ore., claims she was hired to give Gore a $540 massage Oct. 24, 2006, when he was in town to talk about climate change.

“He turned from Mr. New Age into a pervert,” she said. “He grabbed me in a big bear-hug embrace from behind and began mauling my breasts.”

Hagerty said she escaped and immediately reported the alleged incident. But cops dropped the case for lack of evidence after Hagerty “canceled multiple interviews.”
