Business Group Challenges Lina Khan’s Agenda at FTC

WASHINGTON—The U.S. Chamber of Commerce is challenging Federal Trade Commission Chairwoman Lina Khan, contending in a series of letters that she is overstepping the agency’s legal authority.

In three letters to the FTC dated Friday, the Chamber cited potential breaches of administrative procedure that it said could be open to legal challenge. It also was set to file more than 30 requests with the FTC under the Freedom of Information Act, seeking documents that could include Ms. Khan’s personal communications and those of her staff.
