The Federal Trade Commission sued PepsiCo on Friday, alleging that it has engaged in illegal price discrimination by giving unfair price advantages to one large retailer at the expense of other vendors and consumers.

Outgoing agency Chair Lina Khan has filed a raft of measures during her last week in office.

The commission alleges that the retailer, whose name was redacted in the statement from commissioners, received “unfair pricing advantages” that were not made available to others.
