Singapore (CNN) -- A police investigation into one man's death has now become an issue between two countries. Singapore's Foreign Ministry on Sunday said it was "deeply disappointed" by the attempt of two U.S. senators to block funding to the country's state-backed Institute of Microelectronics in a dispute over the investigation into the death of American who had worked there. U.S. Sens. Max Baucus and Jon Tester of Montana recently introduced a measure to block U.S. funding to the institute until U.S. Attorney General Eric Holder certifies that the FBI had full access to all evidence related to the death of research engineer Shane Todd.
