On August 2, 2017, the President signed into law the "Countering America’s Adversaries Through Sanctions Act" (Public Law 115-44) (CAATSA), which among other things, imposes new sanctions on Iran, Russia, and North Korea.
The CAATSA-Related Sanctions represent the implementation of multiple legal authorities. Some of these authorities are in the form of executive orders issued by the President. Other authorities are public laws (statutes) passed by The Congress. These authorities are further codified by OFAC in its regulations which are published the in Code of Federal Regulations (CFR). Modifications to these regulations are posted in the Federal Register.
