''No one did more for Netanyahu than me': Trump bares all in chat.
In an interview with journalist Barak Ravid for his new book 'Trump’s peace: The Abraham Accords and the Reshaping of the Middle East,' former U.S. leader says he has not spoken with ex-PM after he congratulated Biden on his win; 'He made a terrible mistake, f*** him,' he says.
“Nobody did more for Bibi. And I liked Bibi. I still like Bibi," he says, referring to Netanyahu by his nickname. "But I also like loyalty. The first person to congratulate Biden was Bibi. And not only did he congratulate him, he did it on tape. And it was on tape."
"The first person who congratulated Joe Biden, because this was an election in dispute, it's still in dispute. The first person who congratulated was Bibi Netanyahu, the man that I did more for than any other person I dealt with…Bibi could have stayed quiet. He has made a terrible mistake”.
