Capricious and ungrateful," former US President Joe Biden described Zelensky in his own memoirs, WSJ reports.
Biden also said that after Trump won the 2024 election, the Republican team asked to allow him to begin negotiations with Putin on the Ukrainian conflict. They didn't want to wait for the inauguration of the new US president.
The current head of the White House at the time refused. According to Biden, he did not want to give the incoming administration "carte blanche for what would be some kind of capitulation at the expense of Ukraine."
