Trump doubts Russia used biological weapon in Siberian plague case, keeps probe open

President Trump publicly cast doubt on claims that Russia used a biological weapon in the Siberian plague incident, while keeping the U.S. investigation open and signaling a forthcoming call with Putin. The statement marks a notable softening of prior U.S. rhetoric, though the underlying facts remain unverified. The outcome could affect U.S.-Russia relations and global biosecurity norms.
