Dutch lawyer is first person to be sentenced in Mueller probe, gets 30 days in prison
Alex van der Zwaan, who worked with Gates and former Trump campaign chairman Paul Manafort while he practiced law at a large international firm, admitted to lying and failing to turn over emails to Mueller's team in February.
He was wrapped into the special counsel's investigation last fall after his firm, Skadden Arps, began to cooperate in an investigation of Manafort and Gates' alleged contact with Ukrainians and Russians during the 2016 election. He lied in his first voluntary interview with investigators in November, and according to both Judge Amy Berman Jackson and prosecutor Andrew Weissmann on Tuesday, was "caught red-handed."
