What if it was a Sham Marriage?

And this man is not the president's biological father, but married his pregnant mother and briefly served as legal father in name only?

I can see where he might not want his father's pleas for financial assistance and scholarship help splashed across the NYT. Nor to go out of his way to read the documents. The legal father served his purpose, early in life and early in the political life too. That book's already been written...

Just a little critical thinking this Father's Day.
