In a Wednesday letter to the CEOs of Amazon and Facebook, four congressional Democrats called on the tech giants to stop trying to \u0022strip Federal Trade Commission (FTC) Chair Lina Khan of her authority to enforce antitrust law.\u0022\r\n\r\n\u0022The real basis of your concerns appears to be that you fear Chair Khan\u0026#039;s expertise and interpretation of federal antitrust law.\u0022\r\n—Democrats\u0026#039; letter\r\n\r\nPresident Joe Biden appointed the 32-year-old \u0022antitrust trailblazer\u0022 to lead the FTC after she was confirmed by a bipartisan Senate vote in June. Amazon and Facebook responded by pressuring Khan to recuse herself from antitrust matters involving the companies—provoking the new letter from Sens. Elizabeth Warren (D-Mass.), Richard Blumenthal (D-Conn.), and Cory Booker (D-N.J.), along with Rep. Pramila Jayapal (D-Wash.).\r\n\r\nThe lawmakers warn (pdf) Amazon\u0026#039;s Andy Jassy and Facebook\u0026#039;s Mark Zuckerberg that \u0022your efforts only add to the perception that you are attempting to bully your regulators, disarm the FTC, and avoid accountability rather than to strengthen ethics standards, and you should cease these efforts immediately.\u0022\r\n\r\nProgressive advocates have cheered the rise of the former Columbia Law School associate professor, and praised Biden and senators for empowering someone with her background.\r\n\r\n\u0022Lina Khan has proven herself as one of the fiercest and most effective critics of Big Tech,\u0022 Demand Progress executive director David Segal said after her Senate confirmation. \u0022She not only understands the threat these monopolies impose, but how to utilize the tools of government to hold them accountable and break them up.\u0022\r\n\r\nIn their letter to Big Tech CEOs, the lawmakers write that \u0022both of your companies have engaged in a coordinated attack to discredit Chair Khan on ethics grounds, even—in the case of Amazon—going so far as to request immunity from any future antitrust investigations.\u0022\r\n\r\n\u0022The real basis of your concerns appears to be that you fear Chair Khan\u0026#039;s expertise and interpretation of federal antitrust law,\u0022 they continue. \u0022To argue that federal ethics laws preclude Chair Khan from exercising her expertise is illogical and inconsistent with the plain language of the relevant statutes and with FTC ethics officials\u0026#039; interpretations of recusal requirements.\u0022\r\n\r\n\u0022There is no basis for her recusal under the current federal ethics statute or FTC precedent,\u0022 the letter states. \u0022Your efforts to sideline Chair Khan appear to be nothing more than attempts to force an FTC stalemate that would allow you to evade accountability for any anti-competitive behavior.\u0022\r\n\r\n\r\n\r\nThe letter adds that \u0022if you are serious about ending conflicts of interest in Washington, you can show your sincerity by supporting legislation that makes federal ethics rules and enforcement even more stringent.\u0022\r\n\r\nIn December, Warren and Jayapal reintroduced the Anti-Corruption \u0026amp; Public Integrity Act, explaining at the time that their proposal \u0022is more urgent than ever in order to rein in corruption, strengthen ethics, end lobbying as we know it, improve the integrity of our judiciary, reform campaign finance laws, and finally ensure that we put people over profits and communities over corporations.\u0022\r\n\r\nAlong with calling out Amazon and Facebook\u0026#039;s attacks on Khan, the four lawmakers sent the companies a list of questions \u0022in order to ensure that your own respective legal and governmental efforts are meeting appropriate ethics standards and are free of conflicts of interest,\u0022 requesting responses by August 18.\r\n\r\nThe battle over Khan\u0026#039;s power in her new role comes as lawmakers, federal regulators, and advocacy groups have continued to not only raise antitrust concerns about Amazon and Facebook but also express various other critiques of both companies\u0026#039; business practices.
