This bill establishes the United States Secret Service Reserve Fund to ensure the agency can continue its critical protection duties during a lapse in appropriations. The fund is specifically designated to cover necessary expenses, including the salaries of employees directly involved in protecting individuals identified in section 3056 of title 18, United States Code. The Director of the Secret Service may use these funds only during an appropriations lapse, for a period not exceeding 30 days or until the lapse ends, whichever occurs first. An initial appropriation of $106,000,000 is provided from the Treasury to establish this reserve. Any unused funds remaining by December 31, 2026, must be returned to the Treasury by January 31, 2027, and a report detailing the fund's use must be submitted to relevant congressional committees.
