Persons who threaten democracy in Ukraine also represent a threat to the United States, according to a 2014 executive order issued by President Obama following Russia’s invasion and seizure of the Crimean region.
In fact, the resulting threat to US national security and foreign policy is so severe as to constitute a “national emergency,” said Executive Order 13660, which remains in effect. Those who engage in “actions or policies that undermine democratic processes or institutions in Ukraine” may have their assets blocked by the United States.
Several more individuals were designated for sanctions this year under the executive order, according to the latest report to Congress from the Secretary of the Treasury. See Periodic Report on the National Emergency with Respect to Ukraine, September 6, 2019.
