Senate Democrats call for Trump administration to unveil details of TSMC plant deal

Democratic lawmakers on Tuesday urged the Trump administration to answer “serious questions” about Taiwan Semiconductor Manufacturing Co Ltd’s plans to build a U.S.-based $12 billion plant, flagging national security concerns and potentially undisclosed subsidies. TSMC, the world’s biggest contract chipmaker and supplier to U.S. tech giants such as Apple Inc, announced the project last week, in a move trumpeted by Commerce Secretary Wilbur Ross as signaling a “renaissance in American manufacturing” fueled by President Donald Trump. In a letter addressed Tuesday to Ross and Defense Secretary Mark Esper, top Senate Democrat Chuck Schumer and two colleagues said they “strongly support” efforts by the administration to “on-shore” semiconductor plants in the United States.
