Did Trump commit an impeachable offense using this sentence?

Trump launched another attack on Democrats including Schiff over the Senate impeachment trial earlier on Sunday, saying on Twitter “he has not paid the price, yet, for what he has done to our Country!”

What price?..Is that a threat? How can that be interpreted?...What does that mean? What kind of "price" is to be paid?..Why say that?

You know, Donald Trump hasn't got a clue. Much too stupid to know, that what he really needs to do is to "shut up." at least for a while. .... That is it, and that is all.
