It'll be interesting to see how this turns out.
One salient fact to keep in mind is that the MAGA faction clamoring for release of the Epstein files are not die-hard Trump acolytes and thus aren't [as] subject to Trump's Jedi "look over there, Obama bad!" mind tricks; these folk are a mix of conspiracy theorists/promoters (e.g., MTG, Bongino) , right-leaning podcasters/viewers (e.g., Joe Rogan), and those who hate Trump but support him because his policies generally align with theirs (e.g., Tucker, Murdoch).
Should Ghislaine lie about the Epstein files to congress, it's an open question whether this will satisfy this faction.
