Requires the Director to increase the annual number of hours spent training by Secret Service officers and agents. Authorizes the Director to: (1) construct facilities at the Rowley Training Center necessary to improve the training of officers of the U.S. Secret Service Uniformed Division and agents of the Secret Service Presidential Protective Detail, and (2) hire not fewer than 200 additional officers for the Division and 80 additional agents for the Detail. Requires the Director to devise and adopt improved procedures for: (1) evaluating vulnerabilities in White House security and threats to persons protected by the Secret Service, including threats posed by unmanned aerial systems or explosive devices; and (2) evaluating the ways technology may be used to improve White House security and the response to threats to persons protected by the Service.
