Rep. David Wu was spotted Saturday night sans tiger suit. The Oregon Democrat dined at Bibiana with a thirtysomething female professional acquaintance. They got together to “talk shop,” a spokesman told Yeas & Nays. Wu made headlines in February when reports surfaced that his staff had confronted him for bizarre behavior, including emailing around a Halloween picture of himself dressed in a tiger suit. On Saturday, he stuck with khakis and a blazer.
