Trump at Davos signals Greenland framework, Fed chair speculation, and a homes-first push

At Davos, President Trump said a framework for a Greenland deal will last 'forever,' hinted at narrowing the field for the next Federal Reserve chair, backed a 10% credit-card interest cap for a year, said he hopes there won’t be further U.S. action in Iran while not ruling it out, and pressed to block large institutional buyers from snapping up single-family homes to keep ownership affordable for regular buyers.
