That came from a BBC story linked below that several sources claim is from Russian disinformation. I don't know what the actual facts are. I do accept a pretty much universal evaluation that the Ukraine has been a very corrupt country and Zelensky has done little or nothing to correct that.
Even so I am pretty sure President Trump (and the EU) have no intention of allowing Putin to annex the Ukraine.
Our best best is a peace treaty that holds, however that can be obtained within reason, and then live with a cold war between those two countries.
The BBC story:

". . .The Pentagon said on Thursday that it has operated 46 biolabs in Ukraine handling dangerous pathogens, after previously dismissing the charges as Russian propaganda. . ."
Washington has been urged to come clean over its biolab program in Ukraine after the Department of Defense admitted its existence. The Pentagon said on Thursday that it has operated 46 biolabs in Ukraine handling dangerous pathogens, after previously dismissing the charges as Russian propaganda.

The Pentagon released a new fact sheet about the government’s efforts to lessen the threat of weapons of mass destructio

The Pentagon didn’t ‘admit’ that there are 46 US-funded biolabs in Ukraine
