Hur's comments on Biden's memory in documents case draw criticism
• Special counsel Robert Hur criticized Biden's memory and cognitive ability as "hazy", going beyond his mandate to assess the classified documents case.
• Former Obama DOJ officials called the comments "gratuitous", inconsistent with neutral legal analysis.
• Hur noted lack of evidence Biden intentionally retained documents, but put that 200 pages into the report.
• Some experts defended Hur's comments as explaining why no charges despite initial suggestion of criminality.
• White House said lack of evidence should have featured more prominently than "inappropriate criticism".
