Donald Trump came to Rudy Giuliani's defense on Saturday, a day after declaring that he did not know if the former mayor of New York was still his personal advocate and that the pressure was still mounting in the # 39, impeachment investigation related to Giuliani's work in Ukraine.

Giuliani "may seem a bit rough on the edges", Trump tweeted"But he is also a great man and a great lawyer".

The president did not say that Giuliani was still his personal lawyer. The former mayor said Friday that he was there.

Giuliani is under pressure for his extra-governmental role in Trump's attempts to pressure Ukraine to investigate Joe Biden, a potential opponent in the 2020 election, for allegations of baseless corruption involving son of the former vice president.

Two US citizens of Soviet origin, both of Giuliani's associates, were arrested on Wednesday for suspicion of election campaign funding violations while they were trying to leave the United States with a one-way ticket.

On Friday, the New York Times reported that Giuliani was himself under federal investigation for his work in Ukraine and Ukraine.

Trump recently seemed to be beginning to distance himself from Giuliani, as the president's allies wanted the former voluble mayor to shut up.

The investigation of impeachment led by House Democrats accelerates, fueled by the Ukrainian scandal and causing the State Department and senior diplomats in a clutter of court hearings. committees, subpoenas and political battles with bare hands.

On Friday, former US ambassador to Ukraine, Marie Yovanovitch, testified in camera in front of House committees conducting the tax investigation, after defying the White House's efforts and the State Department to block it.

Speaking about his controversial dismissal, Yovanovitch said: "The prejudice will occur when private interests circumvent professional diplomats for their own benefit, and not for the public good".

As he was leaving the White House for a campaign rally in Louisiana, the president was asked if Giuliani was still his personal advocate.

"I do not know," said Trump. "I did not talk to Rudy. I spoke to him yesterday briefly. He is a very good lawyer, and he was my lawyer.

Giuliani told the Washington Post that he still represented Trump. Saturday, a Yahoo News reporter said that he had "just texted" Giuliani, who said "he never feared Trump would throw him away and assign information that a flaw could be committed by people who" flee to become mean. "

Analysts have questioned Giuliani's current description as Trump's lawyer, given the seemingly non-legal nature of his work. Giuliani suggested that the solicitor-client privilege would protect him from Congressional scrutiny. This notion has been questioned.

Trump's former personal attorney, Michael Cohen, is serving a three-year sentence for crimes, including election campaign violations, which he says have been ordered by his boss. This month, it was reported that Cohen wanted to write a revealing book once he would have regained his freedom.

Saturday morning, after leaving the White House for his golf course in Virginia, Trump tweeted"It is now the goal of the legendary 'buster of crime' and the greatest mayor in New York history, Rudy Giuliani. He may seem a bit rough at the edges, but he's also a great guy and a great lawyer.

Giuliani, 75, served as mayor of New York from 1994 to 2001 and earned praise for his leadership in the aftermath of 9/11. In 2012, he briefly ran for the Republican presidential nomination. Before embarking on politics, he was a tough and prosperous American lawyer for the Southern District of New York – the office that now invests him.

"Such[-]in the United States, "insisted Trump Saturday. "Deep state. Shameful!"

The reference to "the deep state" referred to a popular theory of far-right conspiracy that postulates the existence of a permanent government of intelligence officials and bureaucrats, dedicated to thwarting the agenda of Trump.

The former president of the Trump campaign, the White House strategist and Breitbart News' supreme leader, Steve Bannon, one of the leading artisans of the conspiracy popularization, have publicly stated that none of this it was true and that the theory was "for nut cases".
