WASHINGTON — US President Donald Trump said Friday that he would be “very angry” if Russian opposition figure Alexei Navalny was poisoned, adding that he had no reason to doubt Germany’s findings that a nerve agent was used. Speaking to reporters at the White House, the president said it was necessary to “look very seriously” at the poisoning. The United States had previously conveyed its “grave concern” to Russia after the German finding. Europe and the United States came down hard on Russia for last month’s poisoning of Navalny earlier in the week. On Wednesday, Germany said Navalny was the “victim of a crime,” after determining that he was poisoned with a Soviet-era nerve agent, Novichok. It is the same poison allegedly used to try to kill a former Russian spy and his daughter in England in 2018. — Agencies
