This resolution aims to restrict the use of public funds for official travel by Senators during periods of government shutdowns. It specifically prohibits Senators from using amounts from their Official Personnel and Office Expense Account to cover the costs of official travel. This prohibition applies whenever there is a lapse in appropriations for one or more federal agencies, meaning funds cannot be obligated or expended for such travel or reimbursement. The measure seeks to ensure that Senators do not incur travel expenses funded by taxpayers during times when federal agencies are unfunded.
