Alex van der Zwaan was turned over to Dutch authorities, the officials added, a day after he was released from a low-security federal prison in Allenwood, Pennsylvania, after serving 30 days. He also was ordered to pay a $20,000 fine.
Van der Zwaan, a 33-year-old lawyer formerly with international law firm Skadden Arps, pleaded guilty to lying to investigators about his interactions and records of communication with top Trump campaign official Rick Gates and a person with ties to a Russian intelligence service during the 2016 presidential campaign. Van der Zwaan had worked with Gates and former Trump campaign chairman Paul Manafort as they attempted to spin a report on Ukrainian politicians done by the law firm.
Immigration and Customs Enforcement officials say van der Zwaan arrived in the Netherlands Tuesday.
