Trump says 'we don't think' Russian plague is bio-weapon

US President Donald Trump said Wednesday that the death of a Russian plague laboratory worker did not appear to be linked to a biological weapon. "We don't think so. We're going to find out soon enough, but we don't think so," Trump told reporters in the Oval Office when asked if a "bio-weapon" was involved. Russia warned earlier against "false" information as reports emerged of a second suspected case. The US and UN have urged Russia to be more transparent.
