An elderly, ultra-secretive Chicago businessman has given the largest known donation to a political advocacy group in U.S. history — worth $1.6 billion — and the recipient is one of the prime architects of conservatives’ efforts to reshape the American judicial system, including the Supreme Court.

Through a series of opaque transactions over the past two years, Barre Seid, a 90-year-old manufacturing magnate, gave the massive sum to a nonprofit run by Leonard Leo, who co-chairs the conservative legal group the Federalist Society.
