Both cases are narrow — accusations of making false statements. One of those cases is against Mr. Sussmann, whom Mr. Durham has accused of lying during a September 2016 meeting with an F.B.I. official about Mr. Trump’s possible links to Russia.
(Mr. Durham says Mr. Sussmann falsely said he had no clients, but was there on behalf of both the Clinton campaign and Mr. Joffe. Mr. Sussman denies ever saying that, while maintaining he was only there on behalf of Mr. Joffe — not the campaign.)
