(CNN) – The Portland Police Bureau interviewed former Vice President Al Gore last week in connection with a re-opened investigation into charges he attempted to sexually assault a massage therapist, CNN affiliate KATU reports.
Citing a law enforcement source, KATU reports the former vice president sat down with investigators while he was in San Francisco last Thursday to answer questions about the charges.
In a statement to CNN, Gore spokeswoman Kalee Krieder said, "Our office has no comment as the process is ongoing."
A spokesperson for the Portland Police Bureau did not return CNN's request for comment
Portland police authorities re-opened their investigation earlier this month into a massage therapist's allegation that Gore had "unwanted sexual contact" with her in 2006.
"In reviewing this case, we have determined there were procedural issues with the 2009 investigation that merit re-opening the case," the police department said in a statement announcing the investigation had been re-opened. "There should have been command level review at the time on the specifics of this case and decisions on whether the investigation should go forward."
A renewed investigation "will only benefit Mr. Gore," Kreider said at the time. "The Gores cannot comment on every defamatory, misleading, and inaccurate story generated by tabloids. Mr. Gore unequivocally and emphatically denied this accusation when he first learned of its existence three years ago. He stands by that denial."
The therapist told police in a prepared statement in January 2009 that she was "repeatedly subjected to unwanted sexual touching" by Gore during an October 2006 massage she performed on the former vice president at his hotel room. The department initially concluded there was not enough evidence to bring charges against Gore.
