Watch'The Lost Calls of 9/11' Sunday, Sept. 5 at 10 p.m. ET on Fox News. President Biden on Friday signed an executive order calling for the review of classified information related to the terrorist attacks on Sept. 11, 2001, and the ultimate declassification of some documents. The president's move was lauded by families of victims who died on that fateful day nearly 20 years ago, and was seen as a supportive gesture toward many who have long sought the records in hopes of implicating the Saudi government. The order, coming little more than a week before the 20th anniversary of the attacks, is a significant moment in a yearslong tussle between the government and the families over what classified information about the run-up to the attacks could be made public. That conflict was on display last month when some 1,800 relatives, survivors and first responders came out against Biden's participation in 9/11 memorial events if the documents remained declassified.
