US President Donald Trump has claimed victory as the Democratic Party-controlled House of Representatives concluded its third public hearing on the impeachment proceedings against him for allegedly abusing his office for political gain in the run up to the 2020 presidential election.

The impeachment hearings are an effort by Democrats to establish whether Trump withheld US military aid to Ukraine to pressure the country’s President Volodymyr Zelensky into announcing a corruption inquiry into Joe Biden, Trump’s leading Democratic rival in the poll.

“A great day for Republicans, a great day for our Country! In the end we will win and save our Country from certain destruction,” Trump tweeted soon after the House Select Committee on Intelligence concluded its third public impeachment hearings on Tuesday.

Later in the day, Kurt Volker, former special envoy to Kyiv, and Tim Morrison, another top NSC aide, testified before the powerful House Committee.

“Today’s second hearing is over, and the Democrats’ central allegation in this impeachment sham has again been completely debunked,” White House Press Secretary Stephanie Grisham said at the conclusion of the testimonies.

“Specifically, Ambassador Volker confirmed under oath that he had no indication whatsoever of anything that resembled a quid-pro-quo, corroborating his previous deposition testimony that ‘there was no linkage like that,” she said.

“With the Democrats’ poll-tested ‘quid-pro-quo’ and ‘bribery’ narratives in shambles, the American public should not be forced to endure this charade for one more second,” Grisham said.
