A 9/11 widow is demanding the U.S. government stop shielding Saudi Arabia from accountability.

Terry Strada heads the group 9/11 Families United, which is suing the kingdom for its alleged role in the 2001 attacks. She publicly criticized former presidents George W. Bush, Barack Obama and Joe Biden during the 25th anniversary commemoration in New York last week, and called on the Trump administration to pressure the Saudi government to come clean.
