No, she said "There are biological research laboratories in Ukraine." Not run by the US.
And that doesn't mean bioweapons. There's a biological research lab across the hallway to me, doing research on aging and genetics. Biological lab can mean almost anything, but uneducated minds (no personal anttacks) are easy to mislead with a simple youtube video.
Ukraine has not developed, nor used, any bio-weapons even after 401 days of this supposedly 3-day war. And stop it with the youtube videos, they're not evidence. They're just evidence of YOUR brainwashing.
