U.S. Rep. David Wu (D-Ore.) acknowledged today in a statement to WW that he used prescription painkillers  last fall in the run-up to his election campaign, a period that is now the subject of intense national scrutiny.

As first reported by WW on the afternoon of Feb. 18, the Democratic congressman behaved bizarrely in a string of unusual pre-election incidents that included the Oregon lawmaker sending late-night emails and odd photos. That stretch caused close political advisers to stage two "interventions" before the Nov. 2 election. Sources tell WW the aides were worried about Wu's health and urged him to seek psychiatric care.

Wu's statement today about the painkillers—prescribed by a doctor—offered further details about the stress he was undergoing one week before the election.
