In what some say was essentially a promotional press release for John Bolton’s book, The New York Times reported on Sunday that the former national security adviser will claim that President Donald Trump tied aid to Ukraine to an alleged promise by the country’s leaders to investigate the Bidens.

It was another “bombshell” according to the corporate and pro-Democrat Party media and served the Democrats’ strategy to insist on witnesses, particularly Bolton, to be called for the Senate impeachment trial.

Even if everything Bolton says about Trump in his upcoming book were true, it still would not rise to the level of an impeachable offense, Trump defense team member Alan Dershowitz said on Monday.

Dershowitz, a Harvard law professor and a Democrat, argued that even if the “quid pro quo” is true, that still “would not constitute an impeachable offense.”

When he fired Bolton after repeated policy feuds, Trump tweeted: “His services are no longer needed at the White House. I disagreed strongly with many of his suggestions, as did others in the Administration.”

A policy difference, Dershowitz emphasized, is not criteria for impeachment. “That’s a criteria for deciding who you’re going to vote for,” he told the Senate on Monday.

“Nothing in the Bolton revelations, even if true, would rise to the level of an abuse of power or an impeachable offense,” Dershowitz said.

“That is clear from the history, that is clear from the language of the Constitution. You cannot turn conduct that is not impeachable into impeachable conduct simply by using words like quid pro quo and personal benefit.”

During opening arguments by Trump’s legal team at the Senate impeachment trial on Monday, Dershowitz, a constitutional law scholar, addressed the contents of a leaked manuscript from Bolton’s book.

Bolton appeared to give the “quid pro quo” the Democrats and media have been clamoring for by saying Trump tied the Ukraine aid to an investigation into Joe Biden and his son, Hunter.

Fred Fleitz, who served in 2018 as deputy assistant to the president and to the chief of staff of the National Security Council, is advising Bolton to withdraw his upcoming tell-all book.

In an op-ed for Fox News, Fleitz emphasized the “importance of protecting a president’s confidential discussions with his senior advisers.”
