Rudy Giuliani says that he has ‘smoking gun’ proof that Joe Biden’s son Hunter broke the law while conducting business in Ukraine, and that the Obama administration illegally sought dirt on former Trump campaign manager Paul Manafort.

President Trump’s personal attorney appeared on Fox News on Saturday night and claimed that he had lined up three witnesses ready to ‘name names’ of former Obama officials who illegally sought information about Manafort.

Giuliani also told Fox News that he has a ‘memo’ proving his claims, though he declined to share it with his interviewer, Jesse Watters.

The former New York City mayor claimed that Andriy Telizhenko, Konstantin Kulik, and Nazar Kholodnytsky are willing to testify under oath that in January 2016, the National Security Council asked Ukraine for damaging information about Manafort.

Telizhenko, a 29-year-old Ukrainian man who once worked in the country’s embassy in Washington before resigning in June 2016, told Giuliani last year that the diplomatic mission intervened to help Hillary Clinton in the presidential election.

He also told Giuliani that when Joe Biden was Barack Obama’s vice president, he pressured the Ukrainian government to drop an investigation into Burisma, an oil and gas company that named Biden’s son, Hunter, to its board of directors while his father ran the administration’s Ukraine policy.

According to the Globe and Mail, Telizhenko told Giuliani that he was asked by Ukraine’s ambassador to the United States to find damaging information about Manafort.

Telizhenko also told John Solomon, an opinion writer for The Hill, that he personally attended a meeting with Obama administration officials in January 2016.

The meeting, which included figures from the NSC, FBI, State Department, and the Justice Department, was called to allegedly pressure Ukrainian anti-corruption officials to revive a probe against Manafort.

Telizhenko claims that the Obama officials asked the Ukrainians to look into alleged payments made to Manafort by the political party of ousted Ukrainian President Viktor Yanukovych, an ally of Russian President Vladimir Putin.

Manafort, a longtime Trump adviser, earned millions of dollars while acting as a consultant to Yanukovych for nearly a decade.

Manafort was Trump’s campaign chairman from May to August of 2016.

He stepped down after a Ukrainian lawmaker divulged details contained in a so-called ‘black ledger’ of alleged off-the-books payments made by Yanukovich’s Party of the Regions.

Manafort, who earned millions for his consultancy work in Ukraine, was among the recipients listed in the ledger, which was corroborated at the time by anti-corruption investigators.

He is currently serving a seven-and-a-half year sentence in a federal correctional facility in Pennsylvania for tax fraud, bank fraud and other charges stemming from Special Counsel Robert Mueller’s probe into Russia’s meddling in the 2016 presidential election.

Kulik, a former deputy head of the Ukraine prosecutor general’s international affairs office, and Kholodnytsky, who is currently Ukraine’s top anti-corruption prosecutor, both claimed they witnessed corruption by Democratic operatives in Ukraine during the 2016 election.

So far, no evidence has been produced to support their claims.

‘They (Obama officials) asked foreigners for dirty information on an American citizen who was going to be involved in a political campaign,’ Giuliani said on Fox News on Saturday.

‘If it’s good enough for Donald Trump Jr to be investigated for a year-and-a-half, what about all these NSC members who worked for Obama, worked for Biden?’

The investigation into Don Jr that Giuliani was referring to was the Mueller probe into alleged Russian meddling in the 2016 elections.

The two-year probe found that there was insufficient evidence to charge the Trump campaign with colluding with the Russian government, which is alleged to have tried to derail Hillary Clinton’s candidacy.

Both the Russian government and the Trump campaign have denied the allegations.

Giuliani also claims to have a 'smoking gun' proving that Hunter Biden was involved in a money laundering scheme

Earlier this week, Trump was acquitted in an impeachment trial in the Senate after the House of Representatives filed two articles of impeachment.

The president was impeached after he withheld military aid to Ukraine while demanding that its government investigate the Bidens.

Trump is also alleged to have sought a Ukrainian investigation into the so-called ‘Crowdstrike’ conspiracy theory, which holds that Ukraine was in possession of emails deleted by Hillary Clinton.

During his appearance on Fox News, Giuliani also mentioned Alexandra Chalupa, a 43-year-old Ukrainian-American who once worked for the Democratic National Committee as a consultant.

Guliani, without evidence, claims that Chalupa told Telizhenko that the ‘black book’ which lists Manafort as a recipient of large payments from Yanukovych was ‘intended to blow the Trump campaign up.’

‘That’s gonna destroy the Trump campaign,’ Giuliani quotes Chalupa as saying.

Chalupa, who had extensive contacts in Ukraine, told POLITICO that she began sharing information she had collected about Trump’s alleged ties to Russia.

She began to share the information with Clinton campaign officials as well as with Ukraine’s ambassador to Washington at the time, Valeriy Chaly.

Telizhenko has claimed that he was instructed by one of Chaly’s top aides at the Ukrainian embassy, Oksana Shulyar, to help Chalupa with researching connections between Trump, Manafort, and Russia.

‘Oksana said that if I had any information, or knew other people who did, then I should contact Chalupa,’ Telizhenko told POLITICO in January 2017.

‘They were coordinating an investigation with the Hillary team on Paul Manafort with Alexandra Chalupa.

‘Oksana was keeping it all quiet’ but ‘the embassy worked very closely with’ Chalupa, Telizhenko said.

Shulyar has denied working with Chalupa on anything related to Trump or Manafort.

Giuliani also alleged that he has a ‘smoking gun’ which proves that Hunter Biden was guilty of money laundering.

The former mayor claimed that he had an official document sent by the Latvian government to the Ukrainian government alleging that Hunter Biden was ‘under investigation for [a] corruption affair.’

Giuliani then alleged that $14.8million was sent from Ukraine to a company in Latvia ‘disguised as a loan.’

‘Then it goes from Latvia to another company [in Cyprus] disguised as another loan,’ Giuliani says.

Giuliani claims to have documents proving that Hunter Biden broke the law.

'Look, the government has been so lax in investigating, it's pathetic,' Giuliani said.

'I mean ... when I was a U.S. attorney ... the day Joe Biden made that boastful announcement ... the investigation would have begun the next day for bribery.'

Giuliani was referring to Biden boasting that he used $1 billion in U.S. loan guarantees to force Ukraine into firing its top prosecutor Viktor Shokin, a man considered corrupt by most international bodies.

Shokin has since claimed he was investigating Burisma Holdings, a company where Hunter Biden was paid handsomely for sitting on the Board of Directors

Earlier this week, the Treasury Department handed over sensitive financial information about Hunter Biden to congressional Republicans, despite previously refusing to give Trump's tax returns.

Republican Senators Charles Grassley and Ron Johnson released a letter they wrote to Secret Service Director James Murray seeking documents on the former vice president's son immediately after the vote to acquit President Trump in his impeachment trial.

The highly confidential information on Hunter Biden was reportedly handed over to Grassley, the Senate Finance Committee Chairman, and Ron Johnson, the Homeland Security Committee Chairman.

A Democrat on one of the committees conducting the investigation told Yahoo News that the '''evidence'' of questionable origin' was handed over to the influential senators.

Sen. Charles Grassley at the Capitol on Thursday, who announced the probe in Hunter Biden, has been a firm backer of President Trump

Last year Treasury Secretary Steve Mnuchin blocked a Democratic request in November for the president's tax filings, saying Democrats had no legitimate legislative purpose for seeking the documents.

Mnuchin said in a letter to Democrats last April: 'The legal implications of this request could affect protections for all Americans against politically-motivated disclosures of personal tax information, regardless of which party is in power.'

But that did not apply to the non-tax financial information that may relate to the son of former Vice President Joe Biden - a Trump political rival he is seeking to tie to corrupt business dealing in Ukraine.

Trump's bid to spark and investigation into the Bidens led to the impeachment proceedings which saw the president acquitted in the Republican Senate this week.

Grassley and Johnson are seeking information on any security detail provided to Hunter Biden, as well as travel aboard government aircraft.

In particular they were looking for suspicious activity reports filed relating to Biden with the Treasury Department by financial institutions.

In the letter the lawmakers wrote they are 'reviewing potential conflicts of interest posed by the business activities of Hunter Biden and his associates during the Obama administration' - particularly in Ukraine and China, where he had business dealings.

Ashley Schapitl, a spokeswoman for the highest-ranking Democrat on the Finance Committee, Senator Ron Wyden, said the granting of the Biden request was a 'blatant double standard'.

She said in a statement to Yahoo: 'Applying a blatant double standard, Trump administration agencies like the Treasury Department are rapidly complying with Senate Republican requests - no subpoenas necessary - and producing ''evidence'' of questionable origin.

'The administration told House Democrats to go pound sand when their oversight authority was mandatory while voluntarily cooperating with the Senate Republicans' sideshow at lightning speed.'

The letter by Grassley and Johnson underlined that the president is getting the investigation he wanted, after his request for the president of Ukraine to do him a 'favor' and investigate the Bidens and the 2016 elections prompted a House Democratic impeachment inquiry.

Democrats called it cheating and inducing foreign interference in the US elections, but Republicans said it was not an impeachable offense.

One of the trip coming under scrutiny was Hunter Biden's trip aboard Air Force Two along with his father to China in 2013.

Every Senate Republican other than Mitt Romney of Utah voted to acquit, and Trump brandished headlines of his acquittal at the congressional prayer breakfast on Thursday morning.
