It wasn't one statement. This was early in the invasion so I was glued to the press conferences. It was deliberate messaging delivered more than once. If there's transcripts you could grep search for inflation.

  "I don’t believe NBER has lied and to blame inflation on fiscal stimulus that largely occurred two years ago seems outright bad thinking. Especially to then blame the current administration for it. Inflation is going on all over the world. It’s not Biden’s fault. There’s a collection of reasons and mechanisms at play and Biden can only do so much."

I'm not sure what you think you're arguing against. Never said that it's one hundred percent down to fiscal policy from two years ago (although both loose fiscal and monetary policy of Trump and Biden are undeniably a non-trivial part of it -- money supply and inflation are inextricably linked). I also wasn't saying it was mostly Biden's fault.
