Family members of the victims of the 11 September 2001 terror attacks have called on President Joe Biden to stay away from memorial events unless he declassifies files about the attacks.

Nearly 1,800 people signed a letter calling on him to release documents that they believe implicate officials from Saudi Arabia in the plot.

They say that if he refuses, he should not attend ceremonies next month to commemorate the 20th anniversary…

“We cannot in good faith, and with veneration to those lost, sick, and injured, welcome the president to our hallowed grounds until he fulfils his commitment,” says the letter from family members, first responders and survivors.
