Republicans are celebrating because the New York Post claimed that the New York Times has admitted that the Hunter Biden laptop is authentic. That is not what the New York Times said.
The New York Times said that the laptop was alleged to be owned by Hunter Biden and that experts say at least some of the emails on the laptop are authentic emails of Hunter Biden. The New York Times did not say anyone has confirmed the laptop in question was actually owned by Hunter Biden (but that has not been ruled out).
I suspect some Republican or Russian hacked Hinter Biden’s email account and put a copy of many of the emails on a laptop and left it at the repair shop, but that is just my suspicion.
Here is a link to the actual New York Times article:
