Not a fan of Tulsi but she didn't *literally* claim there were "bioweapons" though, this was twisted by MSM. She said biolabs, which is the official stance of the U.S. and something they were concerned about prior to the invasion. It's the difference between medical research and military research. 

There was some concern about possible soviet era pathogens as well but that is less clear.

There were bio labs. That’s confirmed. 

America says their medical research facilities. Russia says they’re some whacky subversive shit. 

There are bio labs though. There’s lots of biology labs.

Edit: they were also mostly funded by the US but it isn’t like we went over there and built and American only gated facility
