According to Special Counsel Robert Hur's report on President Biden's mishandling of classified documents released Thursday, Biden could not remember key details, such as when he was vice president, during interviews with investigators. 

Hur has been investigating Biden's improper retention of classified records since last year. The papers included classified documents about military and foreign policy in Afghanistan, among other national security and foreign policy records, which Hur said implicated "sensitive intelligence sources and methods." He announced he would not seek criminal charges against Biden.

The report, however, also contains an eye-opening portion on how Biden struggled to remember when he served as vice president in the Obama administration while being interviewed for the investigation. Additionally, Hur's office believed Biden's lawyers would use those "limitations" in his recall if it went to trial.

"In his interview with our office, Mr. Biden's memory was worse," the report states. "He did not remember when he was vice president, forgetting on the first day of the interview when his term ended ('if it was 2013 - when did I stop being Vice President?'), and forgetting on the second day of the interview when his term began ('in 2009, am I still Vice President?')."
