- President Donald Trump vented rage Monday on Twitter, denying his ex-national security advisor John Bolton's reported claim that the president withheld military aid to Ukraine in order to secure investigation into his political opponents.
- But Trump flatly denied the account from Bolton, who left the White House in September amid a public dispute with the president over whether he resigned or was fired.
- Later Monday morning, Republican Sen. Mitt Romney of Utah told reporters, "I think it's increasingly likely that other Republicans will join those of us who think we should hear from John Bolton."
President Donald Trump vented rage on Twitter just hours before his Senate impeachment trial was set to resume Monday, denying his ex-national security advisor John Bolton's reported claim that military aid to Ukraine was frozen in order to secure investigation into Trump's political opponents.
Trump's pushback came amid growing pressure for the Republican-majority Senate to allow witnesses to testify in the trial.
The New York Times reported Sunday that Bolton, in his upcoming book "The Room Where It Happened," wrote that Trump personally tied a nearly $400 million aid package to Kyiv to an investigation of former Vice President Joe Biden and his son Hunter. CNBC has not seen a copy of Bolton's manuscript.
But Trump flatly denied the account from Bolton, who left the White House in September amid a public dispute with the president over whether he resigned or was fired.
"I NEVER told John Bolton that the aid to Ukraine was tied to investigations into Democrats, including the Bidens," Trump tweeted early Monday morning. "In fact, he never complained about this at the time of his very public termination."
"If John Bolton said this, it was only to sell a book," Trump claimed.
At the White House later Monday, Trump told reporters that he has not seen a copy of Bolton's manuscript. But he maintained that Bolton's reported allegations are "false!"
Democrats have held Bolton up as a key witness who must be heard in the trial. And the handful of Republicans seen as being moderate enough to side with the Democrats on witnesses appeared to be taking Bolton's reported claims seriously.
Republican Sen. Mitt Romney of Utah told reporters Monday morning that "I think it's increasingly likely that other Republicans will join those of us who think we should hear from John Bolton."
Sen. Susan Collins, R-Maine, released a statement saying the reports on Bolton's book "strengthen the case for witnesses."
They "have prompted a number of conversations with my colleagues," Collins said.
Republicans hold a 53-47 majority in the Senate. Democrats need a simple, 51-vote majority to have their requests for witnesses and documents approved. But Republicans have compiled their own list of witnesses, including Hunter Biden and the whistleblower whose complaint about Trump's July 25 call with Ukraine's leader sparked the impeachment proceedings.
Senate Minority Leader Chuck Schumer, D-N.Y., said Monday morning that the new reports erase even a "shred of logic left to not hear witnesses and review the documents."
It remains highly unlikely that two-thirds of the Senate will vote to remove Trump, as the Constitution requires.
Democratic House managers, led by House Intelligence Chairman Adam Schiff, D-Calif., laid out their case last week for Trump's conviction and removal from office on charges of abuse of power and obstruction of Congress, both related to his Ukraine dealings. Trump's legal team began their defense on Saturday and are set Monday to continue arguing that the president did nothing wrong.
Bolton had been asked to testify during the House impeachment inquiry, but he refused to appear before the Democrat-led committees leading the impeachment investigation. He was not subpoenaed then; the House Intelligence panel said in a Nov. 7 statement that "we have no interest in allowing the Administration to play rope-a-dope with us in the courts for months."
In early January, however, Bolton said that he would testify in the trial if he was subpoenaed by the Senate.
Trump falsely tweeted Monday that "The Democrat controlled House never even asked John Bolton to testify."
The Republican-majority Senate will vote on whether to include additional witnesses and documents after both sides have concluded their opening statements.
It's unclear how likely the chamber is to approve that step; at the start of the trial, Schumer proposed amendments to the trial rules to issue subpoenas for key witnesses, including Bolton, but each was voted down.
"I think the timing of all of this is very very suspect" White House press secretary Stephanie Grisham said in a Fox News interview earlier Monday. "We stand by exactly what we've been saying all along."
Bolton's attorney, Charles Cooper, said in a statement Sunday that "It is clear, regrettably, from The New York Times article published today that the prepublication review process has been corrupted and that information has been disclosed by persons other than those properly involved in reviewing the manuscript." Cooper was referring to the review process by the White House's National Security Council.
Trump, meanwhile, asserted in subsequent tweets Monday that the memorandum of his July 25 call with Ukraine President Volodymyr Zelenskiy supported his position. Zelenskiy in that call was asked by Trump to "look into" the Bidens and a debunked conspiracy theory that Ukraine, not Russia, meddled in the 2016 election.
Trump also contrasted his administration with former President Barack Obama's by noting that Zelenskiy's government received lethal aid, and bought Javelin anti-tank missiles from the U.S.
