From this:

An Arkansas commercial developer confirmed his role in a no-cost "incentive deal" packaged by former Arkansas Gov. Mike Huckabee to attract a Mexican Consulate to Little Rock.

...Bruce Burrow told WND his commercial real estate company acquired the land and developed the Mexican consulate building in Little Rock at the request of Huckabee [and at no profit in a "public-private" deal], in a deal the then-governor engineered to make sure he snared the Mexican consulate away from other states.

...Arkansas Republican state legislator Rick Green objected to Huckabee using taxpayer funds in the scheme.

...Green told WND that two legislative study groups he helped organize this past summer concluded Arkansas has more illegal immigrants per capita than any other state and that its Hispanic illegal immigrant population is the fastest growing of any state in the nation.

..."We estimated that $410 million per year from Arkansas is sent back to Mexico alone, just in remittance payments," Green noted.

Much more on the questionable nitty-gritty of the deal at the link.
