On Tuesday, the three Democrat-led House committees overseeing the probe sent a letter to Mulvaney asking him to appear for a closed-door deposition on Friday.
Their letter reads, “Specifically, the investigation has revealed that you may have been directly involved in an effort orchestrated by President Trump, his personal agent, Rudolph Giuliani, and others to withhold a coveted White House meeting and nearly $400 million in security assistance, in order to pressure Ukrainian President Volodymyr Zelensky to pursue investigations that would benefit President Trump’s personal political interests, and jeopardized our national security in attempting to do so.”
The House Democrats also warned that if Mulvaney doesn’t show up for depositions, they might use that against Trump in the impeachment inquiry.
The letter cited an Oct. 17 press conference in which Mulvaney was asked about whether the United States held back aid to Ukraine.
The inquiry is centered on whether Trump held military aid to Ukraine to exert pressure on Kyiv to investigate former Vice President Joe Biden and his son, Hunter. Trump has frequently denied the claims.
Speaking to reporters on Friday, President Trump said he would like to see Mulvaney testify in the public phase of the House-led impeachment inquiry.
“I’d love to have him go up,” he said, reported AP, adding that he doesn’t want to validate an unfair process.
“I don’t want to give credibility to a corrupt witch hunt,” Trump told AP.
