Washington, D.C. – Sen. Mike Lee (R-UT), joined by Senators Amy Klobuchar (D-MN), Ted Cruz (R-TX), and Richard Blumenthal (D-CT), has introduced the Competition and Transparency in Digital Advertising Act. The bill would restore and protect competition in digital advertising by eliminating conflicts of interest that have allowed the leading platforms in the market to manipulate ad auctions and impose monopoly rents on a broad swath of the American economy.
