Chip giant Taiwan Semiconductor Manufacturing Co. plans to invest $100 billion in the United States, President Donald Trump said Monday, on top of $65 billion in investments the company had previously announced.

TSMC, the world’s biggest semiconductor manufacturer, produces chips for companies including Apple, Intel and Nvidia. The company had already begun constructing three plants in Arizona after the Biden administration offered billions in subsidies. Its first factory in Arizona has started mass production of its 4-nanometer chips.

Trump, who appeared with TSMC’s chief executive officer C. C. Wei at the White House, called it a “tremendous move” and “a matter of economic security.”

Kroger Chairman and CEO Rodney McMullen has resigned after an internal investigation into his personal conduct.

Kroger, the nation’s largest grocery chain, said Monday that the investigation into McMullen’s personal conduct was unrelated to the business, but was found to be inconsistent with its business ethics policy.

Board member Ronald Sargent will serve as chairman and interim CEO, effective immediately.

Cincinnati-based Kroger said its board was made aware of the situation on Feb. 21 and immediately hired an outside independent counsel to conduct an investigation, overseen by a special board committee.

The company said that McMullen’s conduct is not related to its financial performance, operations or reporting, and did not involve any Kroger associates.
