Purported Archives letter on extent of classified material previously at Mar-a-Lago

Former President Donald Trump allegedly had more than 700 pages of classified material in his possession,

according to a purported May 10 letter from the National Archives to a lawyer representing Trump.

The purported text of the letter was posted by conservative journalist John Solomon on Monday evening

The 700 pages of classified material referenced were found in the 15 boxes that the Archives retrieved from Mar-a-Lago in January, according to the letter.

Trump had authorized Solomon as one of his liaisons to the National Archives to review documents from his presidency.

The posted version of the letter confirms ABC News' previous reporting that documents with the highest levels of classification, including some labeled "Special Access Program" were found.

"As the Department of Justice’s National Security Division explained to you on April 29, 2022: There are important national security interests in the FBI and others in the Intelligence Community getting access to these materials.

According to NARA, among the materials in the boxes are over 100 documents with classification markings, comprising more than 700 pages," the letter reads.
