A group 1,800 family members of Americans who died in the Sept. 11th attacks has written President Biden urging him not to visit any memorials to the incident until he agrees to declassify government information on the role of Saudi Arabia. The families and people directly impacted by the attacks are demanding Biden uphold a campaign statement to err on the side of putting out government information – and say they won't support him visiting Ground Zero to mark the 20th anniversary of the attacks. 'Twenty years later, there is simply no reason – unmerited claims of “national security” or otherwise – to keep this information secret,' the letter signed by 1,800 family members and others said. A group of 1,800 Sept. 11th families say they cannot 'in good faith' welcome Biden to visit 9/11 memorials unless he has met a commitment to release government information on any role by Saudi Arabia 'We understand President Biden's desire to mark the solemn occasion of the 20th anniversary at Ground Zero. However, we cannot in good faith, and with veneration to those lost, sick, and injured, welcome the president to our hallowed grounds until he fulfills his commitment,' they wrote. Brett Eagleson, who's father Bruce Eagleson was killed in the attack on the World Trade Center, and other signatories point to Biden's nuanced commitment in a 2020 letter to the families, who have also brought litigation against the government of Saudi Arabia seeking compensation. 'I intend to be a President for all Americans, and will hear all of their voices. The 9/11 Families are right to seek full truth and accountability,' Biden told them. 'I will direct my Attorney General to personally examine the merits of all cases where the invocation of privilege is recommended, and to err on the side of disclosure in cases where, as here, the events in question occurred two decades or longer ago,' he said. Brett Eagleson, who's father Bruce Eagleson was killed in the attack on the World Trade Center, helped organize the letter US Senator Kirsten Gillibrand, Jill Biden, Democratic presidential candidate Joe Biden and New York Governor Andrew Cuomo attend the 19th September 11 commemoration ceremony at the National September 11 Memorial & Museum in New York, September 11, 2020. The signers note Biden's desire to 'mark the solemn occasion at Ground Zero' Biden issued a nuanced commitment in writing on release of Sept. 11th information The families want any government information on Saudi support for the Sept. 11th attacks Biden said the Trump Administration had invoked state secrets to prevent the release of information, and said he would adhere to prior Obama Administration standards, where privilege, if invoked, 'should be narrowly tailored––that is, used only to the extent necessary to protect against the risk of significant harm to national security.' 'Further, it states that the privilege may not be invoked in order to prevent embarrassment to a person or organization,' Biden wrote. The families accuse the government of concealing information that has emerged since the Sept. 11th Commission issued its report. 'Since the conclusion of the 9/11 Commission in 2004 much investigative evidence has been uncovered implicating Saudi government officials in supporting the attacks,' they write. 'Through multiple administrations, the Department of Justice and the FBI have actively sought to keep this information secret and prevent the American people from learning the full truth about the 9/11 attacks.' The 9/11 Commission looked at Saudi Arabia's role, but did not issue a finding of direct government support – although the largely Saudi hijackers had financial backing from numerous saudis, including Osama Bin Laden. 'The Commission staff found no evidence that the Saudi government as an institution or as individual senior officials knowingly support or supported al Qaeda; however, a lack of awareness of the problem and a failure to conduct oversight over institutions created an environment in which such activity has flourished,' according to the report. In February, Biden's administration released the 2018 report on the murder of journalist and Washington Post columnist Jamal Khashoggi by Saudi agents inside the Saudi consulate in Istanbul, Turkey.
