That statement makes this story at "The Hill" seem rather odd, since they're claiming opposition research against Mr. Arcuri's "non-opponent" Richard Hanna was underway in March, and probably earlier:
According to U.S. Immigration and Customs Enforcement (ICE), the DCCC has issued Freedom of Information Act (FOIA) requests for any violations, citations or complaints against businesses associated with Louisiana candidate Chris Gorman, New York candidate Richard Hanna and Illinois candidate Marty Ozinga.
Requests looking into Gorman’s and Ozinga’s numerous businesses were still pending in late July, while the one looking into Hanna Construction was closed in March.
With all the concern over illegal immigration I certainly hope Mr. Arcuri takes a close look at the vineyard he's visiting this week. After all, it's estimated that 70% of the migrant agricultural workers in New York are here illegally. I'd hate to think he's turning a blind eye to such a heinous crime right under his nose.
Update: The WKTV story above incorrectly states that Mr. Arcuri stopped all payments to Kristian Stiles in March. His most recent FEC filing shows he continued making payments into April, with a $4000 disbursement on 4/15/2008.
