These are boom times for conspiracy theorists, and one problem is they’re never satisfied. There’s always another cover-up to unravel, or another hidden file somewhere that the evil establishment is hiding. That’s what Trump Justice Department officials are learning to their dismay now that they’re trying to close the books on the prosecution and death of Jeffrey Epstein.

Government investigators ruled years ago that the sex offender killed himself in prison, but many on the political right don’t want to believe it. The skeptics included Kash Patel and Dan Bongino before President Donald Trump chose them to run the Federal Bureau of Investigation. But after what DOJ calls an “exhaustive review,” they turned up no evidence of murder or a coverup to protect Epstein’s clients.

“There was also no credible evidence found that Epstein blackmailed prominent individuals as part of his actions,” the Justice Department and FBI wrote in a memo released last week. “We did not uncover evidence that could predicate an investigation against uncharged third parties.”

Fair enough, except this isn’t good enough for the social-media fever swamps. Laura Loomer, Alex Jones and other conspiracy theorists think Messrs. Patel and Bongino, as well as Attorney General Pam Bondi, must be lying, or have been co-opted, or who knows what.

Bondi “needs to resign,” said Loomer, who is a pal of President Trump.

There’s a lesson here for partisans who think they can ride conspiracies to power. They can easily boomerang on you once you’re in a position to see the real evidence and then have to convince a public that doesn’t trust anyone in power. Welcome to the rotten establishment, Patel and Bongino.
