The inspector general of the intelligence community testified on Friday to congressional investigators that, the so-called whistleblower, who misrepresented President Donald Trump’s appeal to the leader of Ukraine had a prior “professional relationship” with a Democrat candidate for 2020, according to the Washington Examiner.

“The IG said [the whistleblower] worked or had some type of professional relationship with one of the Democratic candidates,” one person with knowledge of Inspector General Michael Atkinson’s testimony told the Washington Examiner.

In another conversation, a second source revealed: “What [Atkinson] said was that the whistleblower self-disclosed that he was a registered Democrat and that he had a prior working relationship with a current 2020 Democratic presidential candidate.”

A third person said, “What [Atkinson] said was that the whistleblower self-disclosed that he was a registered Democrat and that he had a prior working relationship with a current 2020 Democratic presidential candidate.”

Atkinson did not unveil the Democrat presidential candidate’s identity or clarify the nature of the working relationship.

President Trump reacted to the news by tweeting “This is just the beginning, thank you to @ByronYork!”

The report of the auditor raises further questions about the so-called whistleblower and his accusation, which argues that President Donald Trump pressured President Volodymyr Zelenskiy of Ukraine to probe allegations of corruption against former Vice President Joe Biden and his son Hunter Biden.

In late September, the Trump administration told Fox News that the CIA whistleblower “who leveled an explosive accusation against President Trump concerning his talks with Ukraine had ‘political bias’ in favor of ‘a rival candidate’ of the president.”

Atkinson said in an Aug. 26 letter, the officer was found to have harbored “political bias” in favor of a rival political candidate to President Trump.

The Trump-Zelenskiy call prompted House Democrats to initiate a so-called impeachment inquiry into the president—despite the fact that both denied the attempt to prosecute the Biden family.

“I think you read everything. I think you read text. I’m sorry, but I don’t want to be involved to democratic open elections, elections of USA. No, sure, we had I think good phone call. It was normal. We spoke about many things, and I—so I think and you read it that nobody pushed me,” Zelenskiy told reporters at the United Nations earlier this month.
