Right-wing personalities are spreading baseless notion that the U.S. is producing bioweapons in Ukraine, a Kremlin-backed conspiracy theory apparently used to justify Russia's devastating invasion of Ukraine.
The theory, reported by Media Matters, was publicly presented during a Tuesday Senate Foreign Relations Committee hearing in which Sen. Marco Rubio, R-Fla., asked Under Secretary of State for Political Affairs Victoria Nuland whether Ukraine has access to "chemical or biological weapons."
