He had no business saying that when Biden would be far from alone in not recalling every detail in huge range of stuff they discussed. Something you didn’t mention - you meant Republican Special Counsel Robert Hurr. So knock me down, he found a way to get a political attack in where there as no evidence. Unlike the masses of evidence of illegal retention after multiple requests for return were made in Trump’s case.
Biden dealt with retained documents he found he should not have had, with the stunningly underhand tactic of err, contacting the authorities and handing them back.
Trump is not in hot water for merely retaining documents he shouldn’t have had. He’s in a world of trouble because he frustrated all efforts to locate and return them, including denying, lying, hiding, changing locks, destroying CCTV footage and God knows what over a long period.
There is no equivalence here. A snarky, partisan SC making a cheap shot to garner Trump’s affection should have you thinking more critically. Also, contrast what each man would have been doing with those documents.
