The US has sanctioned the President of Venezuela’s Supreme Court and 7 of its other judges. U.S. officials said the sanctions were a response to an incident in March in which the Supreme Court annulled Venezuela’s democratically elected National Assembly, which is controlled by Venezuela’s opposition party.
The sanctions freeze their assets, and prohibit US persons from doing business with them. In the US Treasury’s press release, Treasury Secretary Steven Mnuchin said that “the United States is supporting the Venezuelan people in their efforts to protect and advance democratic governance in their country”.
