4 Presidents

What is the common thread among the only four U.S. Presidents who have been assassinated: Lincoln, Garfield, McKinley, and Kennedy? They were also the only four presidents ever to take money-issuing control away from the private banks and turn it over to the U.S. Treasury. Within a year of each president doing so, they were murdered. And within months of their vice-president successors assuming their offices, they returned the money-issuing power to the private banks. \
