Obama Goes To Ground Zero

Following the death of Osama bin Laden, President Obama traveled to ground zero Thursday to pay tribute to 9/11 victims. Obama visited with their families, New York City emergency responders — and he laid a wreath where the World Trade Center twin towers once stood. Melissa Block talks with NPR's Ari Shapiro, who traveled with the president.
