Fla. gov.: Anti-Cuba law faces challenge Florida gubernatorial candidate Republican Rick Scott participates in a debate at Nova Southeastern University with Democrat Alex Sink in Davie, Florida on October 20, 2010. UPI/Martin Fried TALLAHASSEE, Fla., May 3 (UPI) -- Florida Gov. Rick Scott called a law sanctioning companies doing business in Cuba unconstitutional but now says he will try to enforce it. The law, which Scott signed Tuesday, takes effect July 1, The Miami Herald reported. Under the law, state and local governments will be unable to hire companies with parent organizations that do business with Cuba or Syria. After the signing ceremony, Scott released a statement suggesting the law is both unconstitutional and unenforceable, because the federal government controls interstate and international commerce. A day later, he backtracked somewhat on that position, promising to enforce and defend the law unless it is overturned, the Herald said. Constitutional lawyers have told me that this legislation will be challenged in court. I signed the bill regardless of that fact, and it will become a state law on July 1, 2012," Scott said in a statement Wednesday. As governor, it is my sworn duty to uphold the laws of the state and I will meet any challenge to this law in court as necessary. Scott angered some Cuban-Americans and advocates for change in Syria because he made no mention of his reservations at the signing ceremony. Dr. Bashar Lutfi, a neurologist, attended the signing. "We didn't know this was going to happen," he said. This was not nice of him. U.S. Rep Mario Diaz-Balart, R-Fla., called Scott's letter Tuesday "an ill-conceived statement."
