US President Joe Biden has defended himself after calling Ukrainian President Volodymyr Zelensky as Russian President Vladimir Putin and asserted that it was the “most successful conference” he had attended in a long time. After referring to Zelenskyy as Putin, Biden confused Vice President Kamala Harris and former US President Donald Trump. When asked whether he had concerns about Harris’ ability to beat Donald Trump if he decided not to run again, Biden responded, “Look, I wouldn’t have picked Vice President Trump to be Vice President. But, I think she’s not qualified to President.”

While addressing a press conference after the NATO Summit in Washington, DC, Biden asked the journalists whether they have seen a more successful conference.
