The DOJ announced today that Butina was in contact "with US persons and infiltrating organizations having influence in American politics." Her goal was to advance the goals of Russia.
Speaking at FreedomFest in 2015, Donald Trump took a question from Butina about Russian sanctions.

In answering her question, then-candidate Trump stated that he would "get along very nicely with Putin" and that he thought Russia would need to have sanctions against it.
