>> Special counsel Robert Mueller's Russia probe has yielded its first prison sentence. Alex van der Zwaan, a Dutch lawyer, who once worked closely with former Trump campaign manager Paul Manafort, will spend 30 days in jail for lying to the FBI. At his sentencing in US District Court in Washington on Tuesday, van der Zwaan said he was sorry for giving false answers to FBI agents about his dealings with Rick Gates, a Manafort business partner who also held a senior position in Trump's campaign.
Van der Zwaan, who is the son-in-law of one of Russia's richest men, pled guilty to the charges in February as Mueller intensified his investigation into potential collusion between the Trump team and Moscow. Several others have pled guilty to charges of lying in the probe, including Gates and former national security adviser Michael Flynn.
Van der Zwaan is the first to be sentenced and the first to serve time. The action comes after a court document on Monday revealed Deputy Attorney General Rod Rosenstein last year authorized Mueller to investigate Manafort for possible collusion with Russia in the 2016 race. Manafort goes on trial in July after pleading not guilty to a stream of indictments tied to his business dealings in Ukraine, including fraud and tax evasion.
