Wertsch, Ph.D. (second from left), the Marshall S. Snow Professor in Arts & Sciences and director of the McDonnell International Scholars Academy; and members of the McDonnell Academy. The group toured New York over spring break and learned about the American political system. While there, students also had breakfast with Mayor Michael Bloomberg at Gracie Mansion and met with United Nations Secretary-General Ban Ki-moon.
