"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?')."

"He did not remember, even within several years, when his son Beau died," the report continued. "And his memory appeared hazy when describing the Afghanistan debate that was once so important to him. Among other things, he mistakenly said he ‘had a real difference’ of opinion with General Karl Eikenberry, when, in fact, Eikenberry was an ally whom Mr. Biden cited approvingly in his Thanksgiving memo to President Obama."
