If Giuliani has anything to offer prosecutors to save himself, it would have to be Trump, the only bigger fish left. And it was arguably criminal for the then-president to have used his official powers to try to coerce foreign officials into aiding his reelection campaign. In fact, Giuliani’s admission that he wasn’t conducting foreign policy, but merely helping Trump personally, is exactly what would make the scheme prosecutable. The former guy just might want to rethink stiffing Giuliani on those bills. That’s not the ultimate irony of Giuliani’s predicament. Federal prosecutors in Manhattan tried to get permission last fall for a Giuliani raid but were rebuffed by senior officials serving under Trump. And last June, for reasons still opaque, then-Attorney General William P. Barr ousted the U.S. attorney there and tried to handpick a successor. If any of that was intended to protect Giuliani — or Trump himself — it might end up backfiring spectacularly. If a warrant had been executed before Jan. 20, it’s hard to imagine that Trump wouldn’t have pardoned Giuliani, out of spite, self-interest or both.
