The CARES Act passed the Senate unanimously. If Trump caused inflation due to profligate spending, he did so with plenty of help from Democrats. He couldn't have stopped it even if he wanted to, that's far past the veto proof majority.
Being fiscally conservative in a way that gets no play in the mainstream political discourse, and given how much the current narrative is hanging the now-apparent price inflation on the current administration (including how the incompetent Democratic party is just going along with it!), I'd say it's worth coining a term that points to when that monetary inflation actually occurred. Despite what those benefiting from all of the monetary creation would have you believe, these effects have causes!
Apart from CARES there was also interest rates. I had been cautiously optimistic that Trump was actually going to buck the trend there and continue pulling up from ZIRP (hence the hate from the MSM). But nope, as soon as that line started to go down, it was printing press time. Rates are not under the control of the President directly, but there is obviously significant influence.
There's also the issue of anti-leadership paralyzing society (thus the economy) much more than it had to be. A little positive leadership would have given Trump a shoe-in second term from the war/crisis time boost, but the dude only knew how to continue with the spiteful divisive poor-me whinging from the campaign.
(Related to this subject, I'll give positive credit for the steel tariffs as something that needed to be done. It was yet another spike in prices, but that was really only revealing what ZIRP had already hollowed out)
