"I am afraid it will be on my gravestone. 'Rudy Giuliani: He lied for Trump.' Somehow, I don’t think that will be it," Giuliani said in an interview with The New Yorker.

"But, if it is, so what do I care?" he continued. "I’ll be dead. I figure I can explain it to St. Peter. He will be on my side, because I am, so far … I don’t think, as a lawyer, I ever said anything that’s untruthful."

"I have a sense of ethics that is as high as anybody you can imagine," Giuliani added. "I’ve been doing this forever. I am doing what I believe in. I may not always be right, but I am doing what I believe. And I believe [Trump] has been treated horribly."

Giuliani, who joined Trump's legal team in April, has in recent days sought to clarify or walk back a number of statements regarding talks to build a Trump Tower in Moscow during the 2016 presidential race.

The former New York City mayor said Sunday that Trump remembered having conversations about the real estate project with his former attorney Michael Cohen "throughout 2016" and "as far as October, November."

On Monday, he maintained that his comments about the timeline were "hypothetical."

Cohen pleaded guilty last year to lying to Congress about when negotiations for a Trump Tower in Moscow concluded, among other crimes. Cohen said while pleading guilty that efforts to build a Trump Tower in Moscow lasted until June 2016.

Last week, Giuliani said in an interview on CNN that he "never said there was no collusion" between the Trump campaign and Russia, claiming only that Trump himself was not involved in collusion.

He sought to clarify those comments the next day, issuing a statement that he has "no knowledge of any collusion by any of the thousands of people who worked on the campaign.”
