The demand for President Donald Trump’s impeachment intensified Wednesday with U.S. Democratic presidential contender Joe Biden joining the chorus by breaking his silence on the matter.

According to Biden, the Trump impeachment has become imperative as “Donald Trump violated his oath of office, betrayed this nation and committed impeachable acts in full view of the world and the American people.”

Biden argued that the censure of Trump is essential “to preserve our Constitution, our democracy and our basic integrity.”

This is the first time Biden is speaking on the matter. 

Despite being at the fulcrum of the controversy over Trump’s dealings with Ukraine, the former VP had refrained from making any outright demand for Trump’s impeachment.

However, Biden took the gloves off on Wednesday during a campaign stop in New Hampshire and noted that Trump's words and actions have indicted himself. 

The Democrat front runner hit out at Trump for obstructing justice, his refusal to reply to a congressional inquiry and said Trump already stands convicted. 

Biden, the most probable Democratic presidential candidate is likely to face Trump in the November 2020 presidential election.

Twitter war between Trump and Biden

Biden’s demand for impeachment witnessed a war of words on Twitter between the former U.S. Vice president and Trump. Biden’s reply to Trump slammed the President for not releasing his tax returns.

“Thanks for watching. Stop stonewalling Congress. Honor your oath. Respect the Constitution. And speaking of taxpayers, I’ve released 21 years of my tax returns. You?” Biden wrote.

Trump news highlighted the President’s tweet that wondered why “sleepy Joe Biden who ripped off at least two countries for millions of dollars calling for my impeachment.”

The House of Representatives in the Democratic Party kick-started impeachment proceedings against Trump in September over the President’s phone call to Ukraine President Volodymyr Zelensky in July.

In the phone conversation, according to a whistleblower, Trump sought investigation on Biden and his son Hunter Biden’s business dealings in that country. Hunter Biden was employed with a Ukrainian energy company.

Meanwhile, the White House refused to cooperate with the impeachment inquiry against President Trump.  Former vice president Joe Biden is the leading candidate for the Democratic Party's nomination to face President Donald Trump in next year's election Former vice president Joe Biden is the leading candidate for the Democratic Party's nomination to face President Donald Trump in next year's election Photo: AFP / Olivier Douliery

In a letter to Democratic leaders, the White House rejected the allegation and demand for documents as “baseless and constitutionally invalid.”

Three House committees led by Democrats are investigating Trump and trying to find out if the President deliberately held back aid to Ukraine to force investigation on Joe Biden.
