For several days now, American politics has been on a rather complex matter, involving President Donald Trump and his potential Democratic challenger in the upcoming presidential election, Joe Biden. In a nutshell: According to a US intelligence complaint and subsequent journalistic investigations, Trump put pressure on Ukrainian President Volodymyr Zelensky during a telephone conversation in July to initiate an investigation into Joe Biden and his son Hunter Biden, a former board member of a Ukrainian gas company , According to some, Trump's aim was to beat and discredit his father Biden, a candidate who had been selected at the time to win the Democratic Party's primaries and challenge Trump in the upcoming presidential elections to be held in November 2020.
In the past few days, new details of the story that are puzzling all the major American newspapers have surfaced.
The Complaint From Which It All Began
The case started on August 1
The New York Times Washington Post and Wall Street Journal however, identified the foreign leader in Volodymyr Zelensky, a former comedian who was elected Ukrainian president last April.  Trump's request to Zelensky
At the center of the whole story is a call Trump made to Zelensky on July 25, when Trump called on the Ukrainian president to investigate Joe and Hunter. Biden: Biden's son in fact worked in the years in Ukraine, when his father was vice president of the United States in the government led by Barack Obama. The Wall Street Journal wrote that "about eight times" Trump asked Zelensky to collaborate with Rudy Giuliani, the White House IT security adviser, on the investigation of the two Biden.
The Wall Street Journal said Trump wanted to show that Joe Biden had unlawfully acted as Vice President of the United States and taken positions on Ukraine that had served only to protect his son Hunter. According to Trump and Giuliani, Joe Biden strongly recommended the dismissal of Viktor Shokin, the Ukrainian prosecutor who investigated the Ukrainian gas company in which Hunter Biden was working.
This point is rather controversial. So far, there has been no evidence to substantiate Trump's allegations against Joe Biden, not to mention that the demand to replace Shokin came not only from Biden, but also from Ukrainian anti-corruption agencies, several European diplomats, and the State Department they saw the prosecutor's office as widely corrupt. In fact, Shokin was accused of not doing enough to stop corruption: several Western and Ukrainian officials, for example, believed he had not researched enough about the affairs of the Burisma group, which included Hunter Biden. Saturday, Joe Biden he denied Trump's accusations: "He violates any basic norm for a president, he uses the abuse of power and every element of the presidency to beat me."
The charges against Trump
One of the things that is not clear in this story is how Trump tried to persuade Zelensky to investigate Joe and Hunter Biden
In recent days, American newspapers have focused on one certain hypothesis that could explain the allegedly inappropriate and illegitimate "promise" that Trump gave to a leader stranger. Some fear that Trump has "manipulated US foreign policy" to achieve his goal of initiating the investigation and discrediting Biden. In fact, during the telephone conversation between Trump and Zelensky, the United States had postponed sending new military aid to Ukraine: Trump could have used that lever to approve the resumption of aid and convince the Ukrainian president of what he was doing asked.
Even Trump denied all allegations: He claimed the telephone conversation with Zelensky was "routine" and spoke of "witch-hunt" initiated by American newspapers against him and his government.
The Story of the Promise in the American Election Campaign
As is generally foreseeable, this whole story of pledging to a foreign leader was at the center of the campaign for primaries organized for the presidential election.
Several Democratic presidential candidates have tried to make full use of the allegations against Trump without mentioning too much of Joe Biden, who was being held at the time. I preferred to win the primaries of the Democratic Party. For example, Senator Elizabeth Warren began her rally on Saturday afternoon with a direct attack on Trump, which she had done far more limitedly than other Democratic candidates. Warren, who called for the vote on Trump's impeachment in April, accused the president of "calling on another foreign government to attack our electoral system" after he had already done so with Vladimir Putin's Russia.
At the moment, there are some unclear things in the whole thing. The impact of this story on the election campaign will depend mainly on what will come out in the coming days or weeks, both due to investigations by the US newspapers and investigations by relevant United States Congress officials.
