Well you can get a basic idea on how the Government spends it from this book
Here's an example:
Once again the House and Senate certified the fiscal year 2010 State and Foreign Operations Appropriations Act as “earmark free.” Unfortunately for taxpayers, there are seven earmarks and they were not free – they cost $209.4 million. This is a 56.3 percent decrease in projects from fiscal year 2009, when there were 16 projects, and an 18.2 percent decrease in dollars from the $256 million in fiscal year 2009.
$17,000,000 added by the House for the International Fund for Ireland (IFI). According to information on IFI’s website, the program was established in 1986 to promote economic and social advance and encourage contact, dialogue and reconciliation between nationalists and unionists throughout Ireland. In a review of a glowing book about IFI released in January 2009, author Sean Donlon admitted, “While the fund will continue its work for the next couple of years it would be unreasonable to expect external support thereafter, especially in the current relatively stable political and security situation in Northern Ireland.” On June 17, 2009, Rep. Jason Chaffetz (R-Utah) introduced H.R. 2915, which would prohibit funding for the program amid indications from supporters that IFI will be phased out in the near future. Language in the conference report indicated that fiscal year 2010 would be the last year the United States would contribute to the program. CAGW has identified $281 million for this project since 1995. It appears that only if taxpayers find a four leaf clover will this unnecessary program die.
$17,000,000 this year for dialogue in Ireland....really? $281 million over the last 15 years???
