In the face of the blistering White House letter refusing to cooperate with their probe, Democrats expect they are likely done with any voluntary interviews for most witnesses, according to multiple Democratic sources. And Democrats are now threatening subpoenas to associates of Rudy Giuliani and considering them for current State Department officials, including former US Ambassador to Ukraine Marie Yovanovitch. She is scheduled for an interview Friday, but there are new concerns she won’t appear given that she is still a State Department employee and could face backlash internally if she were to appear voluntarily.
Negotiations are also intensifying over bringing in for an interview the whistleblower whose complaint has upended Trump’s presidency, with new discussions about holding the interview in secret or off site and not disclosing that it happened until after the fact, according to multiple sources familiar with the situation.
