Aaron Schock is about to leave his congressional office.

The Illinois Republican quit his House seat amid swirling controversy over how he spent lots of public money on extravagant outings around the world. The young man has expensive taste and now it might be that he accepted gifts illegally … allegedly.

A grand jury is looking into it. Congress should examine it, too.

Indeed, the Aaron Schock story suggests there might be a giant iceberg under that ethical tip.

Is he the only member of Congress to live large? Might he be the lone member of either legislative chamber to, um, take staffers on outings that go far beyond their official duties?

A part of me seriously doubts he’s alone in this kind of alleged misbehavior.

I don’t intend here to beat up on Aaron Schock. He’s going to face authorities back home in Peoria, Ill. What’s more, his resignation from the House stunned his colleagues; Speaker John Boehner didn’t know Schock was leaving until he actually announced it publicly.

The one-time rising GOP star, though, is leaving some questions that need answers.

Is he the only one who has done the things he’s been accused of doing?

I doubt it. Is Congress ever going to look inward and start a thorough House-and-Senate cleaning?
