The GOP-led House Judiciary Committee on Thursday issued subpoenas aimed at an advertising initiative partnered with the World Economic Forum that claims to fight against “harmful” content online.

In cover letters obtained by The Daily Wire, Chairman Jim Jordan (R-OH) wrote that the Global Alliance for Responsible Media (GARM) and the group that created it — World Federation of Advertisers (WFA) — may be facilitating coordination by its members in a manner that violates U.S. antitrust law.

“To advance our oversight and inform potential legislation related to these collusive practices, the Committee must understand whether, how, and to what extent GARM and WFA facilitate collusion to prevent certain content from benefiting from advertising dollars and to reduce that content’s presence online,” Jordan wrote to King & Spalding, the law firm representing the collectives.
