Today's lesson in congressional etiquette: Don't e-mail pictures of yourself wearing a tiger costume. Oregon Rep. David Wu apologized Tuesday for some questionable behavior just prior to his re-election last fall. "Last October was not a good month, it was very stressful," he told "Good Morning America." "I did some things, I said some things which I sincerely regret now. And as a result of those things, I saw fit to consult professional help." Wu, a seven-term congressman, said he got the counseling he needed and "I'm in a good place now."

Last week, Oregon media reports said Wu's staffers staged an intervention about his mental health and hid him from public view during the last three days of his campaign. They were alarmed by a number of erratic behaviors including a rambling speech, gaining access to a restricted airport area to ask passengers for votes, and sending staffers several pictures of himself in a tiger suit at 1 a.m. from his private congressional account. Six senior staffers have since resigned from his office.

"I think a take-home lesson from this is while they were very, very unprofessional, you shouldn't ever send photographs of yourself in a Halloween costume," said Wu.
