U.S. House Democrats are planning to vote on Wednesday to impeach President Donald Trump a second time, CNN reported citing House Majority Leader Steny Hoyer on Monday. 

Hoyer told his fellow Democrats the chamber would start the impeachment proceedings on Wednesday if Vice President Mike Pence does not respond to a request to invoke the 25th Amendment of the U.S. Constitution to remove Trump from office, a House aide said.

House Democrats introduced an article of impeachment on Monday morning, which charges Trump with "incitement of insurrection." The passage would make Trump, a Republican, the only U.S. president ever to be impeached twice.

Thousands of Trump supporters stormed the seat of Congress last week, forcing lawmakers who were certifying Democratic President-elect Joe Biden's election victory into hiding in a harrowing assault on the heart of American democracy that left five dead.

The violence occurred shortly after Trump urged supporters to march on the Capitol during a rally where he repeated false claims that his resounding defeat in the November 3 election was illegitimate. Many House Democrats and a handful of Republicans say Trump should not be trusted to serve out his term, which ends on January 20.

Democrats formally introduced their impeachment resolution on Monday. It charges Trump with "incitement of insurrection."

"We have a president most of us believe participated in encouraging an insurrection and an attack on this building and on democracy and trying to subvert the counting of the presidential ballot," Hoyer told reporters.

As the House convened on Monday, Republicans blocked an effort to immediately consider a resolution asking Pence to invoke the never-used 25th Amendment of the Constitution to remove an unfit president.

"The U.S. House must never adopt a resolution that demands the removal of a duly elected president, without any hearings, debate or recorded votes," said Republican Representative Alex Mooney, who raised the objection.

The House is expected to vote on Tuesday evening on the resolution for use of the 25th Amendment, which allows the vice president and the Cabinet to remove a president who is incapable of fulfilling his duties.

Pence and his fellow Republicans have shown little interest in invoking the amendment, but House Speaker Nancy Pelosi and other Democrats have tried to ramp up the pressure on them to act against Trump. They called on Pence to respond within 24 hours after passage of the resolution.

"As our next step, we will move forward with bringing impeachment legislation to the floor. The president's threat to America is urgent, and so too will be our action," Pelosi said in a statement.

Trump acknowledged a new administration would take office on January 20 in a video statement after the Capitol violence but has not appeared in public. Twitter and Facebook have suspended his accounts, citing the risk of him inciting violence.

'Good conversation'

Trump reportedly met with Pence Monday evening in the Oval Office, a senior official said, signaling a common front as Democrats press the vice president to have the president removed from office as unfit.

"The two had a good conversation," the administration official said of the meeting, their first since last week's assault on the U.S. Capitol.

According to the official, Trump has no intention of resigning his office before his term comes to an end on January 20.

The official likewise indicated that Pence has no intention of invoking the 25th Amendment of the Constitution to remove Trump as unfit to discharge his duties – as Democrats are demanding.

Trump and Pence "reiterated that those who broke the law and stormed the Capitol last week do not represent the America First movement backed by 75 million Americans," the official said.

The pair "pledged to continue the work on behalf of the country for the remainder of their term," they added.

In an angry speech before the assault, Trump urged his supporters to march to the Capitol and demand that Pence, who was leading a joint session of Senate and House on certifying Joe Biden's victory, must intervene to reverse his election defeat.

Pence refused, and he was ultimately the one who announced to lawmakers Trump's and his loss to Biden and Kamala Harris, the incoming vice president.

Some Trump supporters, furious over Pence's action, were chanting that he should be hanged.
