PORTLAND, Ore. (AP)  A massage therapist accused former Vice President Al Gore of “unwanted sexual contact” at a hotel in October 2006, but no charges were filed because of lack of evidence, law officials said Wednesday.

A lawyer for the woman contacted the police in late 2006, said the Multnomah County district attorney, Michael D. Schrunk. Mr. Schrunk said the woman, who has not been identified, had refused to be interviewed and did not want the investigation to proceed.

But in January 2009, she contacted the police and gave a statement in which she said Mr. Gore had tried to have sex with her during an appointment at the Hotel Lucia. The National Enquirer first reported the accusations on Wednesday.

A spokeswoman for Mr. Gore, Kalee Kreider, said he had no comment. Mr. Gore and his wife announced on June 1 that they were separating.
