For the first time in US history, the U.

S House of Representatives on Wednesday will vote to impeach President Donald Trump for a second time for his role in the deadly siege on the U.

S Capitol last week.

The single article of impeachment seeks to charge the outgoing president with incitements of insurrection.

We're gonna walk down to the capital after he encouraged his supporters to march on the Capitol building to express their anger over an election Trump insists without evidence was stolen from him.

We fight like hell on.

If you don't fight like hell, you're not gonna have a country anymore.

The stage was set for impeachment Wednesday after Vice President Mike Pence rejected an effort to persuade him to invoke the 25th Amendment of the US Constitution to remove Trump.

But the president's support among other Republicans appear to be slipping as a small but growing number of members of his own party break ranks.

At least five House Republicans, including the third most powerful leader, Liz Cheney, said they would vote for Trump's impeachment.

Most vicious witch hunt.

Impeachment of Trump would not immediately remove him from office but would set up a trial in the Senate.

It remained unclear whether such a trial would take place in time to expel Trump from office.

As lawmakers debated the matter, National Guard troops and police were stationed around the capital to provide security.

Some service members, wearing fatigues with weapons at hand, could be seen sleeping inside the Capitol building.
