WASHINGTON (AP) — Treasury Secretary Janet Yellen and Federal Reserve Chairman Jerome Powell have told Congress that more must be done to limit the damage from the coronavirus pandemic. Powell says the increased government support should not trigger unwanted inflation. Both officials struck upbeat notes about the future of the economy in their appearances Tuesday before the House Financial Services Committee. They said while there are encouraging signs of a rebound it is important that government support continue to make sure the millions of people who have lost jobs can return to the labor market. Republican lawmakers expressed concerns about the prospects of run-away inflation.
