Joe Biden has signed an executive order directing the Justice Department to oversee a declassification review of the FBI’s investigation into the 9/11 attack on the US.
The order requires Attorney General Merrick Garland to publicly release any declassified documents on the attacks over the next six months.
In a statement, Mr Biden said that when he ran for president, he made a commitment to ensuring transparency regarding the declassification of such documents and that as the 20th anniversary approaches he is honouring that commitment.
