Former New York Mayor Rudy Giuliani, now President Trump’s personal attorney, told reporters on Tuesday, Dec. 31, he is willing to give testimony at the president’s impending impeachment trial in the Senate.

“I believe that historically, this impeachment will not be called an impeachment. I believe it will be called an illegal coup,” said Giuliani, reports Fox News.

Giuliani said he has plenty of information to impart on corruption involving Ukraine and Democrats, and would “love to try the case.”

“I would testify, I would do demonstrations, I’d give lectures, I’d give summations, or I do what I do best. I try the case,” he told reporters at Trump’s New Year’s Eve party at Mar-a-Lago in Florida. “I’d love to try the case.”

“When the full scope of what happens in Ukraine comes out, there are going to be a lot of Americans who participated in the corruption,” adding “The Bidens took millions of dollars laundered out of Ukraine, and the only reason they’re getting away with it is because you and the press protect them …”

After the president was impeached in December on two articles—obstructing Congress and abuse of power, relating to the phone conversation he had with Ukrainian President Volodymyr Zelenskiy on July 25, Giuliani traveled to Europe where he interviewed witnesses, and his investigation is ongoing.

“What I learned is that the corruption in Ukraine is vast. It’s extensive. It highly involves the Democratic Party, not just in 2016, but for many years,” said Giuliani, describing what he called “American Ukrainian corruption.”

“I’m not going to tell you what I found out until I have a proper forum … but it’s devastating,” he said, adding, “We will figure out the right forum.”

“It will turn out to be a series of criminal acts that will involve the highest levels of the Obama administration,” he said. “And it’s the reason why the Democratic Party is in panic.”
