U.S. President Donald Trump has thanked his Ukrainian counterpart Volodymyr Zelensky for the words confirming there was no pressure during their July 25 phone call, which caused the so-called Ukrainegate in the United States.

"Thank you to President Zelensky. Case over. The Do Nothing Democrats should finally go back to work!" Trump tweeted on December 2 in response to Zelensky interview given to foreign publications, Deutsche Welle's Ukrainian Service reported.

Trump considers the Ukraine subject to be closed against the background of Zelensky's statements. In an earlier tweet, Trump emphasized that Zelensky had reiterated that the U.S. president had in no way acted improperly with regard to Ukraine, including during telephone conversations.

"Breaking News: The President of Ukraine has just again announced that President Trump has done nothing wrong with respect to Ukraine and our interactions or calls," he tweeted.

It was reported that Zelensky, speaking in an interview with a number of media, again denied a 'quid pro quo' with Trump over military aid to Ukraine. "I did not speak with U.S. President Trump in those terms: you give me this, I give you that," Zelensky said in an interview published on Monday, December 2.

The Ukrainegate is under way in the U.S. over a July 25 telephone conversation between Trump and Zelensky. Trump is accused of pressuring Ukraine to launch investigations against his Democratic political rival Joe Biden and his son Hunter, who worked on the board of a Ukrainian gas company from 2014-2019.

The key issue is whether Trump set up a 'quid pro quo' with Zelensky by holding back promised U.S. military aid for Ukraine until the Bidens were investigated. Democrats have also claimed the 'quid pro quo' could be present with the military aid being held for a meeting between Trump and Zelensky in the White House.

In this connection, hearings are continuing in Congress as part of the impeachment inquiry into Trump.
