Trump: Russia claims lab worker death situation is 'under control'

US President Donald Trump acknowledged that Russia has not disclosed many details about the death of a Russian lab worker at a plague research institute but believes its not linked to a bioweapon, adding Moscow says the situation is 'under control.' His comments come as Russia's health watchdog says there is no risk of an epidemic, but global health experts are still urging caution and asking for more transparency and information from Moscow.
