WASHINGTON — The White House and Senate Republicans worked aggressively on Wednesday to discount damaging revelations from John R. Bolton and line up the votes to block new witnesses from testifying in President Trump’s impeachment trial, in a push to bring the proceeding to a swift close.
As the Senate opened a two-day, 16-hour period of questioning from senators, Mr. Trump laced into Mr. Bolton, his former national security adviser, whose unpublished manuscript contains an account that contradicts his impeachment defense. The president described Mr. Bolton on Twitter as a warmonger who had “begged” for his job, was fired, and then wrote “a nasty & untrue book.”
On Capitol Hill, Mr. Trump’s aides circulated a letter informing Mr. Bolton that the White House was moving to block publication of his forthcoming book, in which he wrote that the president refused to release military aid to Ukraine until its leaders committed to investigating his political rivals. That is a core element of the Democrats’ case, which charges Mr. Trump with seeking to enlist a foreign government to help him win re-election this year.
