"We aren’t letting up until we solve this problem, and we are working to ensure more safe formula is available on store shelves nationwide," President Joe Biden said in a statement given to Reuters. "There’s more work to do, but we’re making progress and in the past two weeks, infant formula sales broke post-pandemic records," he said. The shortage of infant formula has become a potent political problem for Biden, who is also struggling to address concerns about high U.S. inflation ahead of the November mid-term elections.
