Congressional Budget Office Cost Estimate: S. 1946, Public Corruption Prosecution Improvements Act [open pdf - 23KB]
From the Summary: "S. 1946 would broaden the coverage of the current laws against public corruption and would increase penalties for such offenses. The legislation would expand the number of offenses relative to fraud committed by public officials that could be federally prosecuted. The bill would authorize the appropriation of $25 million for each of fiscal years 2008 through 2011 mostly for the Department of Justice to investigate and prosecute violators of the bill's provisions. Assuming appropriation of the authorized amounts, CBO [Congressional Budget Office] estimates that implementing the bill would cost $100 million over the 2008-2012 period. S. 1946 could affect direct spending and receipts, but we estimate that any such effects would not be significant."
