As Secretary of the U.S. Department of Homeland Security from 2005 to 2009, Michael Chertoff led the U.S in blocking would-be terrorists from crossing their borders or implementing their plans, if they were already in the country. He also transformed FEMA into an effective organization following Hurricane Katrina. His greatest successes have earned few headlines – because the important news is what didn’t happen. Mr. Chertoff is a magna cum laude graduate of Harvard College (1975) and Harvard Law School (1978). From 1979-1980 he served as a clerk to Supreme Court Justice William Brennan, Jr.
