Mueller investigation - the jailing has started.
Dutch national Alex van der Zwaan has been sentenced to 30 days in prison, two months of supervised release, and will be forced to pay $20,000 in fines for lying to special counsel Robert Mueller's team about his contacts with Trump campaign officials.
Mr Van der Zwaan, 33, is the son-in-law of a Russian oligarch and had entered a guilty plea in February for lying to Mr Mueller's investigators about contacts he had with former Trump campaign chairman Paul Manafort and his deputy Rick Gates. Those interactions occurred while Mr Van der Zwaan was working in Ukraine.
