From Gaetz's Tweet; "the incredible support of so many" is the usual marketing-speak, whether in politics or in business, but the "thoughtful feedback" (coupled with "so many" making clear that there were others) signals the truth well, I think:
I had excellent meetings with Senators yesterday. I appreciate their thoughtful feedback—and the incredible support of so many. While the momentum was strong, it is clear that my confirmation was unfairly becoming a distraction to the critical work of the Trump/Vance Transition. There is no time to waste on a needlessly protracted Washington scuffle, thus I'll be withdrawing my name from consideration to serve as Attorney General.
