Basically, the "I'm opening an investigation into [political opponent] now that election day is a week away" is turning into a classic modern US politico late-election cycle gambit.
Which makes Obama's refusal to investigate Trump in 2016 seem naive at best, and Biden's failure to prosecute Trump immediately after J6 for insurrection criminally negligent.
(btw, weird shit like that makes me think the files Trump kept at Mar A Lago were Epstein files, not "nuclear secrets")
