Secret Service Reauthorization Act of 2017 This bill amends the federal criminal code to: (1) subject the appointment of the Director of the U.S. Secret Service to the advice and consent of the Senate; (2) prohibit knowingly entering an object into any restricted building or grounds to impede or disrupt the orderly conduct of government business or official functions; and (3) prohibit knowingly and willfully threatening to kill, kidnap, or harm former Vice Presidents, their spouses, or their children under age 16 or any person protected by the Secret Service under a presidential memorandum. The Director must increase the annual number of training hours for Secret Service officers and agents. The Director is authorized to: (1) construct facilities at the Rowley Training Center to improve the training of U.S. Secret Service Uniformed Division officers and Secret Service agents, and (2) hire not fewer than 200 additional officers for such division and 85 additional agents for the Secret Service Presidential Protective Detail. The Director shall adopt improved procedures for: (1) evaluating vulnerabilities in White House security and threats to persons protected by the Secret Service, and (2) evaluating the use of technology to improve such security and respond to such threats. The Director is required to evaluate the practicability of equipping agents and officers with weapons other than those currently provided. Provisions of the Presidential Protection Assistance Act of 1976 requiring expenditures above a specified amount by the Secret Service for securing any non-governmental property in addition to the one non-governmental property designated by each protectee to be approved by the House and Senate Appropriations Committees are replaced with provisions requiring the Secret Service to notify such committees of any such expenditures. The Director shall establish an Ethics Program Office. A Secret Service officer may provide armed protective services authorized by statute or pursuant to a presidential memorandum at any place where a general or special election is held.
