It appears that in John Bolton’s book, he explicitly states that Donald Trump withheld aid to the Ukraine to coerce an investigation of political rivals:
President Trump told his national security adviser in August that he wanted to continue freezing $391 million in security assistance to Ukraine until officials there helped with investigations into Democrats including the Bidens, according to an unpublished manuscript by the former adviser, John R. Bolton.
The president’s statement as described by Mr. Bolton could undercut a key element of his impeachment defense: that the holdup in aid was separate from Mr. Trump’s requests that Ukraine announce investigations into his perceived enemies, including former Vice President Joseph R. Biden Jr. and his son Hunter Biden, who had worked for a Ukrainian energy firm while his father was in office.
Mr. Bolton’s explosive account of the matter at the center of Mr. Trump’s impeachment trial, the third in American history, was included in drafts of a manuscript he has circulated in recent weeks to close associates. He also sent a draft to the White House for a standard review process for some current and former administration officials who write books.
Over dozens of pages, Mr. Bolton described how the Ukraine affair unfolded over several months until he departed the White House in September. He described not only the president’s private disparagement of Ukraine but also new details about senior cabinet officials who have publicly tried to sidestep involvement.
The White House did not provide responses to questions about Mr. Bolton’s assertions, and representatives for Mr. Johnson, Mr. Pompeo and Mr. Mulvaney did not respond to emails and calls seeking comment on Sunday afternoon.
Mr. Bolton’s lawyer blamed the White House for the disclosure of the book’s contents. “It is clear, regrettably, from the New York Times article published today that the pre-publication review process has been corrupted and that information has been disclosed by persons other than those properly involved in reviewing the manuscript,” the lawyer, Charles J. Cooper, said Sunday night.
He said he provided a copy of the book to the White House on Dec. 30 — 12 days after Mr. Trump was impeached — to be reviewed for classified information, though, he said, Mr. Bolton believed it contained none.
Mr. Bolton would like to testify for several reasons, according to associates. He believes he has relevant information, and he has also expressed concern that if his account of the Ukraine affair emerges only after the trial, he will be accused of holding back to increase his book sales.
Mr. Bolton also described other key moments in the pressure campaign, including Mr. Pompeo’s private acknowledgment to him last spring that Mr. Giuliani’s claims about Ms. Yovanovitch had no basis and that Mr. Giuliani may have wanted her removed because she might have been targeting his clients who had dealings in Ukraine as she sought to fight corruption.
This has got to be a bit awkward for Trump, McConnell, and their Evil Minions™.
