Congressional Budget Office Cost Estimate: H.R. 3737, Social Media Use in Clearance Investigations Act of 2017 [open pdf - 80KB]
"H.R. 3737 would require the Office of Management and Budget (OMB) to report to the Congress within six months on how social media activity is examined during security clearance investigations and related matters. Based on the cost of similar activities, CBO [Congressional Budget Office] estimates that implementing the bill would cost less than $500,000; such spending would be subject to the availability of appropriated funds. Enacting H.R. 3737 would not affect direct spending or revenues; therefore, pay-as-you-go procedures do not apply. CBO estimates that enacting H.R. 3737 would not increase net direct spending or on-budget deficits in any of the four consecutive 10-year periods beginning in 2028. H.R. 3737 contains no intergovernmental or private-sector mandates as defined in the Unfunded Mandates Reform Act and would impose no costs on state, local, or tribal governments."
