evidence: The recordings capture Biden's two-day interview last October with then-special counsel Robert Hur, who ultimately concluded that while Biden improperly retained classified documents, he shouldn't be charged with any crimes because -- unlike former president Donald Trump, who was indicted for allegedly hoarding hundreds of classified documents and then trying to cover it up -- Biden cooperated with investigators and would likely convince a jury that he made "an innocent mistake." Trump, meanwhile, has denied all charges. [...] "The audio recordings, not the cold transcripts, are the best available evidence of how President Biden presented himself during the interview," the lawsuit says. "The Committee thus needs those recordings to assess the Special Counsel's characterization of the President, which he and White House lawyers have forcefully disputed." [...] "Any privilege that could conceivably apply to President Biden's interview with the Special Counsel was waived when the Executive Branch released a transcript of that interview," the lawsuit argued.
