"Mr. McAllister's extreme hypocrisy is an example of why ordinary people are fed up with politics. A breach of trust of this magnitude can only be rectified by an immediate resignation," he said. "He has embarrassed our party, our state and the institution of Congress."
In 2007 when Vitter's phone number was among those disclosed by the "D.C.Madam" accused of running a prostitution ring, Villere expressed disappointment, but ultimately supported the senator.
"I think if nothing else comes out, and this is all there is, then three weeks from now, this will all be behind (Vitter)," Villere told the Times-Picayune at the time.
The party chair said that he received many emails about Vitter, mostly supporting the senator, and that a "vocal minority" opposed him.
Then, when Vitter faced a primary challenger when he ran for re-election in 2010, Villere backed Vitter.
