Without recommending a specific sentence, prosecutors said Monday that Washington lobbyist Sam Patten should receive credit for his cooperation with the government when he is sentenced this week for failing to disclose to U.S. authorities his past consulting work for a Ukrainian political party.

Patten, a onetime associate of former Trump campaign chairman Paul Manafort, pleaded guilty in August to violating the Foreign Agents Registration Act, an 80-year-old law that came to renewed prominence following Manafort’s prosecution on charges related to his past lobbying work for the Russia-aligned government of former Ukrainian President Viktor Yanukovych. Manafort’s prosecution at the hands of the special counsel’s office, led by Robert Mueller III, marked the beginning of the Justice Department’s renewed scrutiny of advocacy for international clients after decades of lax FARA enforcement.
