Senators Ed Markey (D-Mass.) and Richard Blumenthal (D-Conn.) have asked the Federal Trade Commission to investigate and "Address" the data breach at Home Depot.
The pair are co-authors of a bill, the Personal Data Protection and Breach Accountability Act, to better protect personal information.
Home Depot has confirmed the breach, which the senators say could have affected the company's 2,200 stores and transactions going back to April.
“We are concerned that the retailer’s procedures for detecting and stopping operations to steal customer data are inadequate, and we call on the Commission to investigate whether Home Depot’s security procedures meet a reasonable standard,” Markey and Blumenthal said in a letter to FTC Chair Edith Ramirez.
On Monday, arkey said he wanted an accounting from the company ASAP.
