Crazybutt Steve Stockman is under federal investigation. Not for being wild-eyed crazy, mind you, but for all manner of stuff totally unrelated to being a crazybutt.

Retiring U.S. Rep. Steve Stockman and three of his Capitol Hill aides notified Congress on Wednesday that they have been subpoenaed by a federal grand jury in a criminal investigation.

Stockman, a Clear Lake Republican who this year lost a primary election for U.S. Senate, did not divulge the nature of the federal inquiry. He did not seek reelection to the House.

Since he’s a Republican you know it has to be about money and/or sex. Since Stockman has neither, I would suspect we might be in for a fun ride on this one.

It seems he falsified payrolls and accepted illegal campaign contributions. And that’s just the half of it.

But Stockman thinks he holds a Get Out Of Jail Free card.

Stockman’s mention of House rights and privileges could be a sign that he might invoke the Speech and Debate clause of the Constitution, which precludes members of Congress from being prosecuted for official legislative acts, said Brett Kappel, a Washington, D.C.-based attorney who specializes in campaign finance law and disclosure rules.

So accepting an illegal contribution is an official legislative act? Note: this escape clause applies only to Republicans.
