The main purpose of this legislation, known as the "Closing Bribery Loopholes Act," is to strengthen the legal framework surrounding bribery of public officials and witnesses. It aims to clarify what constitutes an "official act" in the context of bribery, making it easier to prosecute such offenses and ensuring that the law effectively addresses any potential loopholes. One of the key provisions of this legislation is the revised definition of "official act." The new definition expands the understanding of what actions can be considered official duties.
