Article Needs More Explanation of Why Investigation Began

I’ve read and reread the Sittenfeld article in the Alumni Weekly. My question is what started this investigation? Why is the government investigating him in the first place? Did some political rival start this process?

As the reporter points out, it is like my support of a pro-abortion politician because I have heard him say he is pro-choice.
