Is Robert P. Koch related to the infamous Koch Brothers?

1. I don't think so.

Robert P. is CEO of The Wine Institute and a Democrat.

In 1992, German American Koch married Dorothy Bush, the only living daughter of George H. W. Bush, at a private ceremony held at Camp David—the only couple to ever be married there in the nation's history. They have two children plus the two children from her first marriage.
Koch is a Democrat who started his career in politics working for Tony Coelho and was part of his campaign to become House Majority Whip. He would later become staff director for House Majority Leader Richard Gephardt before joining the Wine Institute.[1] Since becoming President and CEO in June 2003, membership has grown 70% to over 1,000 Californian wineries and affiliated businesses which are predominately family owned and operated.
