If you have read the history books, there have been many politicians that have gone to jail over these kinds of ethics.
There is a word in the English language that describes it: Corruption.
Many politicians in Massachusetts have ended their careers going out in handcuffs. We had three state house speakers go down in a row and and they got jail time. The former mayor of Chicopee went to jail, many state house members have gone down. Look at Rhode Island, half the state house is legislating from their jail cells. This is because the FBI investigates state and local politicians and their dirty deeds.
Too bad the FBI cannot do its job and investigate congress, the FCC, and every other federal agency involved in corrupt practices.
We have a state ethics commission in Mass (which is basically a joke). Too bad the federal government doesn't have a similar ethics commission with authority that isn't part of congress.
