Cleveland’s election was accompanied by one of the nastiest scandals in U.S. presidental history. It is undisputed (even by Cleveland) that he was paying child support to a woman named Maria Halpin.
Cleveland’s story was that although the child, by then ten years old, might have been his, Halpin had also been sleeping with several of his buddies. When she became pregnant, claimed Cleveland, he took responsibility because he was the only bachelor.
Halpin’s story was that Cleveland had raped her her after a dinner date, that the child was certainly Cleveland’s, that when the baby was born Cleveland had arranged to have it kidnapped and placed in an orphans’ home, and Halpin involuntarily committed to a mental asylum.
