Do you have a link? What I see was that the payments occurred before the Russian(Vekselberg) was put on the sanctions list. And the Russian link, is that a NY company, whose biggest client is a company controlled by Vekselberg, gave money. There may be dots to connect, but at least on those facts there doesn’t appear to be a sanctions violation.

Possible bank fraud, campaign finance violations, and especially any evidence that the campaign knowingly took money from Moscow…would be serious as you say.
