Obama on Surveillance Through the Years

"Through a combination of action by the courts, increased congressional oversight and adjustments by the previous administration, some of the worst excesses that emerged after 9/11 were curbed by the time I took office.

Throughout his political career, President Obama has expressed a range of views on balancing national security needs with personal rights and freedoms.
