US President calls Volodymyr Zelensky 'Vladimir' confusing Ukraine President with Putin at NATO summit

During the NATO summit, US President Joe Biden incorrectly addressed Ukrainian President Volodymyr Zelensky by calling him by the first name of Russian President Vladimir Putin. Biden said, "Vladimir and I...I shouldn't be so familiar," during a press conference in Vilnius and immediately corrected himself and said, "Mr Zelensky and I,". The clip of Biden wrongly addressing the Ukrainian President immediately went viral.
