Two of President Trump's lawyers told Special Counsel Robert Mueller to back off from his demand for an interview with their client - arguing that the president has a constitutional right to "terminate the inquiry" any time he wishes.
"This case is essentially over", Giuliani told the Fox News Channel. Giuliani has told the Associated Press that the president's legal team believes the special counsel does not have the authority to do so.
Topics of Mr Mueller's obstruction investigation include the firings of both former FBI director James Comey and former National Security Adviser Michael Flynn, as well Mr Trump's reaction to Attorney-General Jeff Sessions' recusal from the Russian Federation investigation. Negotiations between Trump's lawyers and the special counsel on a possible interview have continued ever since.
The rest reflects spending by Justice Department components in support of his investigation, which includes whether President Donald Trump or anyone close to him colluded with Russians.
A spokesman for the special counsel's office declined to comment.

And Nagda said that her organization has "absolutely" noticed an uptick in children being separated from their parents. Clinton said that more than 700 kids have been separated from their parents between October 2017 and April 2018.
President Trump tweeted earlier this month the special counsel probe was a "soon to be $20,000,000 Witch Hunt, composed of 13 Angry and Heavily Conflicted Democrats and two people who have worked for Obama for 8 years, STOP!"
They also contended that nothing Mr. Trump did violated obstruction-of-justice statutes, making both a technical parsing of what one such law covers and a broad constitutional argument that Congress can not infringe on how he exercises his power to supervise the executive branch.
Giuliani told ABC it is an "open question" whether Trump would sit for an interview with Mueller but that the president's lawyers were leaning against having him testify.
In addition to the legal battles, Trump's team and allies have waged a public relations campaign against Mueller and the Justice Department to discredit the investigation and soften the impact of the special counsel's potential findings. But because current Justice Department policy states that a sitting president can not be indicted, Mueller is said to be preparing a report of his findings that he will eventually submit to deputy attorney general Rod Rosenstein. As a result, it is not clear whether statutes criminalizing obstruction of justice apply to the president and amount to another legal limit on how he may wield his powers. And I think they've lost that power.
In a statement to CNN, Giuliani said, "All they get to do is write a report". Trump has argued that the claims predate Manafort's involvement with his Republican campaign.
