Final answer:
The VA uses the Code of Federal Regulations (CFR) to implement and enforce laws passed by Congress.
Step-by-step explanation:
The regulations written by the Department of Veterans Affairs (VA) and used to carry out the laws written by Congress are referred to as the Code of Federal Regulations (CFR).
The CFR contains all the executive agencies' and departments' rules and regulations, and it explains how the legislation will be implemented. Administrative agencies, such as the VA, issue rules within the CFR that are necessary for the enforcement of federal laws and programs.
