It’s basically here:

And from another article:
The White House is not opposed to Nato-member Poland donating some of its used fighter-jets to Ukraine, press secretary Jen Psaki said.
But Psaki has spelt out that the US is not eager to have that happen in the way suggested by Poland yesterday, whereby it would donate the jets to the US and the US would supply them to
Ukrainefrom its massive US-Nato air base in south-western Germany.
Psaki is backing up secretary of state Antony Blinken in a press conference at the state department earlier. Both point out that the logistics are complex but, crucially, it risks the US being drawn in to direct military conflict with
Russia.
So basically good for Poland to give them but without involving US. Sounds dodgy as feck to me.
