Sorry but I couldn't locate the final source, went through my Google search list but no luck finding the  article. In general found estimates from 2009 but thought those to old. Continued and  found an article with more recent figures. This is what and where it was but haven't been able to find it again. It was punlished in The Washington Post as a follow up to a Trump Speech and checking the figures re: cost. The article gave the breakdown of tax dollars paid in as well as out. I don't know if those details were in the speech but the Post indicated it wanted to confirm the stated $113 Billion cost to taxpayers. That was the total cost but the article explained that was a cumulative cost and further noted the actual cost. 113 in total paid out by Fed's, States, Locals. Illegal's paid $14 Billion. Leaving 99 B. Of the 99 B the States and Local Governments paid out 84 B for Education and Health Care. Fed paid out 15 B but article did note for what. Hope you can find it, I couldn't.
