U.S. Rep. Aaron Schock (R-Peoria) should have known better, a political science professor says. Schock is on the griddle for accepting free decorating help for his Washington office, allegedly selling his house in Peoria for above market value to a campaign contributor, and traveling to private events at government expense.

John Jackson at Southern Illinois University says these are not minor mistakes. Those things have been pretty clearly out of bounds now for a good while, so he's been regarded as an outstanding young man with a bright future in politics, and now all of a sudden he's hit a pretty serious bump in the road, he said.

Some of the accusations against Schock involve violations of House ethics rules, while some are against the law.

Jackson says ever since Rep. Dan Rostenkowski, the chairman of the House Ways and Means Committee, was voted out of office in 1994 and eventually went to jail over postage stamp transactions, politicians have been careful about accounting for government, campaign and personal expenses.
