It's not worth the bits this line was printed to screen with.
Trump will do away with the FTC because it stands in the way of their goal of dismantling the executive administration. The only thing JD Vance supports about keeping Lina Khan is keeping her captured and institutionally bound so she cannot bring legislation forward against their agenda as a citizen.
There is absolutely no chance Trump's donors, which include the A16Z clowns, Elon Musk, Larry Ellison, and a lot of anti-regulation people in Silicon Valley, are going to allow Lina Khan to stick around. Vice presidents have no power, and Vance is not on the ticket because Trump is interested in his opinion on the FTC. He's on the ticket because he said he wouldn't have peacefully transferred power like Pence did, and that's the only reason.
