The U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC) has published names of individuals added to the Specially Designated Nationals and Blocked Persons List. These persons have been sanctioned because they are believed to have helped with corruption or supported someone involved in such activities. As a result, their property within the U.S. is blocked and U.S. persons are generally forbidden from engaging in transactions with them. The notice lists individuals primarily linked to Kamlesh Mansukhlal Damji Pattni and is part of OFAC's ongoing sanctions efforts under Executive Order 13818.
Simple Explanation
The U.S. government made a list of people they think were helping with bad behavior, like corruption, and said nobody in the U.S. can do business with them. These people's things in the U.S. are also locked up and can't be used.
