He seems like a perfectly normal liberal Democrat to me.

SALEM, Ore. (AP) — Seven-term Democratic Rep. David Wu faced increasing pressure Wednesday to step down amid a series of bizarre revelations in recent days about his mental health, including a photo he sent to staffers during his re-election bid showing him wearing a tiger costume.

The state Republican chair and one of Oregon’s largest newspapers said Wu should resign, but Wu says he has no intention of quitting.

“He has a really important job, and the citizens of Oregon and the citizens of the congressional district deserve to have a congressman who’s completely focused on serving them and being a great congressman,” Oregon Republican Party Chairman Allen Alley said Wednesday.

Wu said Tuesday that it was “unprofessional and inappropriate” to send pictures of himself wearing a tiger costume to staff members while he was in the middle of a heated campaign last year. He also acknowledged taking two tablets of a pain killer that were given to him by an unnamed campaign donor.

“This was the only time that this has ever happened,” the congressman said in a statement of the pain killer episode. “I recognize that my action showed poor judgment at the time, and I sincerely regret having put my staff in a difficult position.”
