Volker told the Intelligence Committee on Thursday he had alerted Giuliani of receiving untrustworthy information from certain Ukrainian politicians, including the country’s former top prosecutor, regarding the Bidens’ alleged corrupt business dealings during the ex-Vice President Joe Biden’s tenure, the Washington Post reported.
The report added that Volker and other State Department officials also warned Ukrainian officials to stay out of US politics in order to avoid allegations of election interference that could potentially have long-term consequences for Ukraine.
Volker resigned last week following a whistleblower complaint that Trump had asked Ukraine President Volodymyr Zelensky to investigate allegations of corruption by the Bidens.
On September 24, House Democrats launched an impeachment inquiry of Trump based on the whistleblower's complaint that alleges presidential misconduct in the July 25 telephone conversation between Trump and Zelenskyy.
Trump called the move another political witch hunt aiming to reverse the results of the 2016 US presidential election.
