MOSCOW - Russian President Vladimir Putin on Tuesday congratulated Joe Biden on winning the U.S. presidential election after weeks of holding out.Putin's message to Biden came a day after the Electoral College confirmed Biden as the nation’s next president, ratifying his November victory in an authoritative state-by-state repudiation of President Donald Trump’s refusal to concede that he had lost.The Kremlin had said earlier that the Russian president would hold off on congratulating Biden until the winner was officially confirmed.“We are just waiting for the end of the internal political confrontation,” Putin said last month, referring to numerous Republican challenges to the vote count.In his message, Putin wished Biden “every success,".
