Lawmakers turned a Tuesday hearing on President Joe Biden’s handling of classified documents into a proxy battle between the Democratic president and Republican front-runner Donald Trump, as a newly released transcript of Biden’s testimony last fall showed that he repeatedly insisted he never meant to retain classified information after he left the vice presidency.

Special counsel Robert Hur, testifying for more than four hours before the House Judiciary Committee, stood steadfastly by the assessments in his 345-page report that questioned Biden’s age and mental competence but recommended no criminal charges for the 81-year-old president, finding insufficient evidence to make a case stand up in court.

“What I wrote is what I believe the evidence shows, and what I expect jurors would perceive and believe,” Hur said. “I did not sanitize my explanation. Nor did I disparage the president unfairly.”

The transcript of hours of interviews between Biden and the special counsel released Tuesday provide a more textured picture of the roughly yearlong investigation, filling in some of the gaps left by Hur’s and Biden’s accounting of the exchanges. But there was no guarantee the hearing or transcript would alter preconceived notions about the president, the special counsel who investigated him, or Trump, particularly in a hard-fought election year.

While Biden was adamant that he treated classified information seriously, the transcript shows that he was at times fuzzy about dates and details and he said he was unfamiliar with the paper trail for some of the sensitive documents he handled.

The hearing played out just hours before Biden claimed the Democratic nomination and Trump became the GOP standard-bearer. The party lines calcified almost immediately over which leader meant to hang onto classified documents, or rather, who “willfully” retained them — and who didn’t. And Hur was the rare witness vilified all around, by Republicans angry over his decision not to charge the president, and by Democrats for his unflattering commentary about Biden.
