The purpose of this legislation is to change the retirement age for officers of the United States Capitol Police. It aims to provide flexibility in determining when these officers can retire, allowing for a retirement age that can be set between 57 and 65 years old. Key provisions of this law include amendments to existing retirement regulations. Specifically, it modifies the Civil Service Retirement System and the Federal Employees' Retirement System to replace the fixed retirement age of 60 with a range determined by a governing Board.
