Marco Rubio says, US ‘not disputing’ European report blaming Russia for Navalny poisoning

US secretary of state Marco Rubio stated Washington is not disputing a report by five European nations concluding Alexei Navalny was fatally poisoned. The report identified a rare toxin from a dart frog, with Russia identified as the prime suspect. Navalny's widow declared his murder a "science-proven fact" after his death in a Russian penal colony.
