FBI Director Christopher Wray reflects on changes since 9/11
The FBI has made a great deal of changes in its structure and mindset in the 17 years since Sept. 11, 2001. Christopher Wray took the reins of the bureau just over a year ago. He and the men and women who keep Americans safe from terrorism have been busier than ever. Norah O'Donnell spoke to Wray at the 9/11 Memorial and Museum in New York.
