The U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC) has announced the addition of several individuals to its Specially Designated Nationals and Blocked Persons List. These individuals, who are current or former officials of the Venezuelan government, will have their property and interests in property under U.S. jurisdiction blocked, and U.S. persons are generally prohibited from engaging in transactions with them. This action is based on OFAC's determination that the legal criteria for such a designation have been met under executive orders related to the situation in Venezuela.
Simple Explanation
The U.S. government has decided to add some Venezuelan people to a list because they believe these people did something wrong. Now, Americans can't do business with these people, and anything they own in the U.S. is frozen, like when water turns to ice in the freezer.
