Washington is poised to reveal more whistleblowers over what has been described as US President Donald Trump's abuses, and as the House prepares to launch preliminary inquiries into Trump's impeachment of a parliament that could lead to his dismissal. Former Joe Biden and his son Hunter on corruption charges.

According to US media, lawyers representing the first complainant that led to Trump's parliamentary investigation have revealed the existence of two other intelligence officials, including those with first-hand information about Trump's call that pressured Ukrainian President Volodymyr Zelinski to investigate Joe Biden and his son. .

ABC quoted a lawyer as saying that a second reporter had already spoken to the National Intelligence Inspector General, which could confuse Trump and his allies' insistence on questioning the credibility of the first.

The New York Times also revealed the possibility of a second informant with more direct information than the first. The newspaper said the second informant was also an intelligence agent, who was questioned by Inspector General of Intelligence Michael Atkinson to clarify what his colleague told the House of Representatives.

Two top diplomats, on behalf of Trump, sought a deal with Ukraine's president to reopen an investigation into his country on charges related to Biden's son in corruption files in exchange for improving relations between the two countries, according to classified documents presented by former envoy to Ukraine Kurt Volcker. Washington and Kiev.

Republican criticism
The developments come at a time of growing criticism of Republicans calling on Trump to call on China and Ukraine to conduct corruption investigations related to Democratic presidential candidate Joe Biden and his family.

Senate Republicans, Mitt Romney, Sass and Susan Collins, have broken their silence and are concerned about Trump's call for foreign help to target a political opponent in his bid for a new term in next year's election.

Republican Senator Susan Collins said she believed Trump had made a big mistake by asking China to take part in the investigation of a political adversary.

Republican Senator Mitt Romney saw Trump's behavior as a grave mistake. Romney has previously described Trump as a fraud and fraud, and that he is heading the United States towards the abyss, as he put it.

Trump attack
But Trump continued to attack his critics, this time targeting Republican Senator Matt Romney.

Trump tweeted that Romney was "a stupid person fighting me from the start," adding that "if he had worked so enthusiastically before (former President Barack) Obama would have won the presidency, but unfortunately he did not."

Romney lost the 2012 presidential election to Democrat Obama, and the Republican senator last Friday criticized the president's request for China to investigate Biden, one of the leading Democratic candidates to compete with Trump in the presidential election next year.

Trump's attack on Romney was the first on a Republican, after his criticism in the past few days was limited to the Democratic Party and the media over the start of accountability procedures in the House of Representatives controlled by the Democrats.

Three key committees in the House of Representatives issued summonses to the White House to obtain documents related to Ukraine, in order to determine the real motives for the Trump administration's sudden decision to suspend aid worth $ 400 million to Kiev, and whether this is linked to pressure on the Ukrainian president to conduct corruption investigations against Biden and his son .

But Trump has yet to comply with the request, leaving it to his own team of lawyers to make the decision.

Chairmen of the House Foreign Affairs, Intelligence, Oversight and Reform Committees accused the president of stalling, saying he had chosen a course of defiance, obstruction and cover-up, and asked Vice President Mike Pence to submit documents related to Ukraine.

According to an information leak, at least six White House officials have information relevant to the case of Ukraine, which means that the investigation chamber may expand.
