A Florida subsidiary of a Brazilian construction firm is suing the state over a new law barring local governments from hiring companies that do business with Cuba or Syria.

Odebrecht USA has filed its lawsuit in a federal court in Miami, calling the law unenforceable and unconstitutional.

It contends only the federal government and not states has the power to make foreign policy.

Another Odebrecht subsidiary is working on a major project to upgrade the Port of Mariel in Cuba.

Odebrecht USA says it is remote and has nothing to do with the branch working in Cuba.

Florida's Republican Governor Rick Scott signed the anti-Cuba and Syria law last month. He immediately caused an outcry when he said he had doubts whether it is enforceable.
