FBI investigates possible campaign finance law violations

The AP reports that the Feds have opened an investigation into the campaign finances of 3-time Republican Senatorial candidate Christine O'Donnell:

Federal authorities have opened a criminal investigation of Delaware Republican Christine O’Donnell to determine if the former Senate candidate broke the law by using campaign money to pay personal expenses, according to a person with knowledge of the investigation.

The person spoke to The Associated Press on condition of anonymity to protect the identity of a client who has been questioned as part of the probe. The case, which has been assigned to two federal prosecutors and two FBI agents in Delaware, has not been brought before a grand jury.

It is quite possible that her finances should be investigated. On the other hand, will the Feds ever investigate Obama's well-documented acceptance of foreign and undocumented money for his 2008 presidential campaign?
