‘Never Trump’ Senator Mitt Romney on Sunday accused decorated Iraq war veteran and former Democratic Representative Tulsi Gabbard of being a Russian asset and spreading “treasonous lies.”

Gabbard had claimed there are “U.S. funded” bio labs in Ukraine that could be a very real danger if targeted in war.

Multiple fact-checkers have labeled the claims false by saying the bio labs – which do exist – are funded by the U.S. USA Today claims that the labs are owned and funded by Ukraine. Their sources are the U.S. and Ukrainian governments.
