WASHINGTON—The House Oversight Committee has launched an investigation into the four major manufacturers of baby formula, including the makers of Similac and Enfamil, asking for information related to a supply shortage that has left many brands out of stock.
In letters sent to the chief executives of the companies, House Oversight Chairwoman Carolyn Maloney (D., N.Y.) and Rep. Raja Krishnamoorthi (D., Ill.), the top Democrat on the panel’s economic and consumer policy subcommittee, asked when they became aware of the supply shortages and what steps they would take to increase supply.
