In the run-up to the election, Lina Khan, chair of the Federal Trade Commission, was called a dope, partisan and unhelpful by Democrats and Republicans. Democratic donors including the billionaires Reid Hoffman, Barry Lisanlar and Mark Cuban called for her ouster from the agency. Last week, a report from the Republican-led House Judiciary Committee accused her of having a far-left agenda and weaponizing the agency.
Ms. Khan “will be fired soon,” Elon Musk, the owner of X and a supporter of former President Donald J. Trump, wrote on his platform on Thursday.
Few government officials elicited such intense bipartisan attention ahead of the election, making speculation regarding the future of Ms. Khan — nominated in 2021 by President Biden — one of the most avid parlor games in Washington.
The fixation on Ms. Khan, 35, is uncommon for a leader at the long-under-the-radar F.T.C., which regulates companies that subvert competition and deceive consumers. It reflects the high stakes of the Biden administration’s wide-ranging program to dampen the power of America’s biggest corporations — which either presidential candidate could reverse if victorious.
Scrutiny from the F.T.C. and the Justice Department has led to the collapse of billions of dollars in recent corporate deals. Lawsuits filed by the agencies could break up big American brands like Google, Amazon and the parent company of Ticketmaster. Ms. Khan has argued to regulate artificial intelligence, ordered companies to make it easier to cancel online subscriptions and banned noncompete agreements, which stop workers from taking a job with a rival employer.
The backlash from the business world and its Washington allies has been fierce — and it ramped up before the vote.
