Congressional Budget Office Cost Estimate: H.R. 4043, Whistleblower Protection Extension Act of 2017 [open pdf - 86KB]
From the Document: "H.R. 4043 would permanently extend the authority of all Inspector General (IG) offices to hire whistleblower protection ombudsmen. The specific authority to hire such employees has expired. Each of the 72 IG offices of the federal government currently have such an ombudsman. The bill also would create additional responsibilities for the ombudsmen and require additional reporting by IGs, agencies, and the Council of the Inspectors General on Integrity and Efficiency (CIGIE). Information from CIGIE and some IGs indicates that most of the additional responsibilities and reporting requirements in the bill would not impose a significant administrative burden."
