Well, one would expect him to say, "just another false ACCUSATION" not "acquisition". He spelled the words correctly, just didn't use the correct word in the idiom (so to speak).

So, it means he's doing a misspelling of sorts, to look dumb to the intolerant left, and send a message to those who understand "misspellings matter." That would mean he's referring to an acquisition going on right now relating to "Horseface", Avenatti, and Michael Cohen.

Or he could have simply made a mistake.
