Washington - US President Donald Trump lost a legal battle today in an attempt to prevent the publication of his personal and corporate tax returns as part of a criminal investigation in New York.

On Monday, federal judge Victor Marrero rejected the Republican president's argument that the presidents in office are immune to criminal investigations, which would allow the Manhattan District Attorney's Office to have access to eight years of the ruler's statements.

Cyrus Vance Jr., who heads that entity, had issued a grand jury summons to the White House chief accounting firm, Mazars USA, to inquire into such documents, following the criminal investigation carried out on the Trump Organization.

Such research focuses on the payments made during the 2016 elections to Stormy Daniels and Karen McDougal, two women who said they had relations with the then real estate mogul.

Trump's lawyers sued last month to block the citation, claiming that the Constitution makes the presidents in office be immune to all criminal inquiries until they leave the White House.

Those lawyers acknowledged that his argument had not been proven in court, but indicated that the disclosure of the president's tax returns would cause him 'irreparable harm'.

Vance's office, on the other hand, asked the judge to dismiss Trump's lawsuit, because he said a grand jury had the right to 'continue his investigation free of interference and delays in litigation,' and also called him to reject the claim of general immunity

In a 75-page ruling, the magistrate said the president's argument was 'disgusting to the government structure and constitutional values of the nation', adding that the presidents, their families and businesses are not above the law, according to he quoted The New York Times.

Unless Trump can quickly win a delay or revocation of the ruling, Vance could soon begin receiving the requested material, so the lawyers of the head of state have already filed an appeal against today's judicial decision.

The fight for the dissemination of Trump's tax statements has been constant since his arrival at the White House in January 2017, when he became the only American president not to disclose that information since the 1970s.

Because of that, Democrats and various organizations believe that they may be trying to hide details of their real financial value, the source of their wealth and possible conflicts of interest that involve their business partners.
