US Senator Richard Blumenthal said federal budget cuts known as the sequester could damage Connecticut’s significant aerospace industry. The senior senator was in Toulouse, France, on Monday on a trade trip intended to boost Connecticut contracts with Airbus. Without action by President Obama and Congress, the Pentagon spending cuts will occur on March 1. In a conference call with reporters, Blumenthal, a Democrat, said many contracts have already begun. He said the sequester, if it happens, would not end production soon. However, Blumenthal said the impact would be unwelcome.
