In her first year as a United States senator from New York, Hillary and I stood together on the steps of the Capitol as we faced that dark day of 9/11. It was a defining moment for our country. But Hillary knew no terrorist could ever crush the New York spirit or the American spirit. As we worked on the Schumer-Clinton-Mikulski amendment to support our nation's first responders, I saw her steely resolve. She was a champion for victims, for Ground Zero workers and responders, and for fire fighters and first responders.
