"H.R. 3361 would direct the Department of Homeland Security (DHS) to establish aprogram to protect the department's critical assets from insider threats (that is, harmfulactivities by department employees and certain other persons with access to classifiedinformation). DHS is currently carrying out activities similar to those required by the act;thus, CBO [Congressional Budget Office] estimates that implementing H.R. 3361 would not significantly affect spendingby DHS. Because enacting the legislation would not affect direct spending or revenues,pay-as-you-go procedures do not apply.CBO estimates that enacting the legislation would not increase net direct spending oron-budget deficits in any of the four consecutive 10-year periods beginning in 2027."
