Former senior officials of the FBI stand accused of lying to Congress about the investigation into Hunter Biden. The accusation lands on ex-agents who once drew harsh criticism from allies of Donald Trump, and those allies now see a moment of vindication. The claim is that the former officials misled lawmakers when questioned about how the Hunter Biden case was handled. Testimony given to Congress carries legal weight, so a false statement is no small matter. Trump's supporters have argued for years that the bureau's handling of the Biden probe was shaped by political bias. The charges against the ex-officials have handed them what they consider proof of that claim. Washington's political camps are treating the development as the latest round in a long score-settling fight.
