(Rebecca Falconer – Axios) European allies’ findings that Putin critic Alexei Navalny was killed with a rare toxin from poison dart frogs is “troubling,” said Secretary of State Marco Rubio on Sunday, adding the U.S. is “not disputing” the report. The big picture: Rubio told reporters in Bratislava during a visit to Slovakia “we don’t have any reason to question” the report that the U.K., France, Germany, Sweden and the Netherlands issued Saturday, which the Kremlin disputes. The report follows Yulia Navalnaya, the Russian opposition leader’s widow, saying in September that that labs in “at least two countries” separately examined “smuggled” samples of Navalny’s biological material and concluded he had been poisoned. – Russia accused of using dart frog poison on Navalny: What to know
