"I want a trial", he said. By early December, the Judiciary Committee is expected to launch its own high-wire hearings to consider articles of impeachment and a formal recommendation of charges.
His main Democratic nemesis in Congress, House Speaker Nancy Pelosi, is "crazy as a bedbug" for pressing a "scam" impeachment, he fumed.
He also denigrated the testimony of David Holmes, a counselor at the United States embassy in Kyiv.
Giuliani pushed back against testimony in the Trump impeachment inquiry that he'd been labeled a "hand grenade that was going to blow everybody up" by former National Security Adviser John Bolton: "For John to say I'm a hand grenade, then he's an atomic bomb", Giuliani said.
In a series of tweets, Trump urged House Republican allies to "Keep fighting tough", and told them they are "dealing with human scum who have taken Due Process and all of the Republican Party's rights away from us during the most unfair hearings in American History".
Of course, Yovanovitch couldn't hang what she didn't have as the Trump White House didn't even release their official portraits until nine months into his presidency because Trump and Pence kept delaying when to sit for them. And he knows it.
In the interview, Giuliani asked Fox News host Ed Henry, "Do You honestly think I'm intimidated?"
The diplomat said that there "really isn't an American interlocutor" on Ukraine after the resignation of envoy Kurt Volker and the public dressing-down of Taylor.
Those discredited theories have been advanced by Trump himself, who in a July 25 phone call at the center of the impeachment inquiry asked Ukraine's leader to investigate the possibility. Trump insisted he was trying to root out corruption in the Eastern European nation when he held up almost $400 million in military aid to help Ukraine battle Russian aggression.

Mr Holmes said he overheard a phone call on 26 July between Mr Trump and Mr Sondland that is potentially damaging to Mr Trump. Who is interested in this?
In a fresh sign of Republican determination to make the impeachment inquiry about Biden's son Hunter and the latter's paid work for a Ukrainian energy company, the Republican chairmen of two Senate committees have asked the Treasury officials for possible reports of "suspicious activities" between the younger Biden and that firm, Burisma Holdings, Reuters reported on November 22.
At one point in the proceedings, a lawmaker asked her about the testimony of another witness who had described Hill as having at one point become irritated with Gordon Sondland, the U.S. ambassador to the European Union who played a central role in the United States effort to get Ukraine to open investigations. "The United States government reached its conclusion on attributing the DNC hack to Russian Federation in 2016 before it even communicated it to the Federal Bureau of Investigation, long before the Federal Bureau of Investigation ever knocked on the door of the DNC". "He knows what I did was in order to defend him, not to dig up dirt on Biden", Giuliani said.
"What have we learned through these depositions and through the testimony?"
Trump said Ukraine is "known as being the third most corrupt country in the world". He accused the White House of blocking his access to it after he left his post in September. He remains at the White House National Security Council.
He said the White House had blocked and "never returned access to my Twitter".
Trump said he asked why some administration officials were being so kind to Yovanovitch.
That was a reference to Rudy Giuliani, Trump's personal lawyer, who had been pushing for Ukraine investigations.
"Do you think I'm afraid?" he said.
