"Trump and his political allies, some of whom we pass every day in the hallways at work".

"It is denied that the 45th President engaged in insurrection or rebellion against the United States, ' Trump's lawyers wrote".

The brief also cites the First Amendment to defend Trump's baseless claims that Joe Biden won the election through massive fraud - saying there is "insufficient evidence" of whether Trump's claims were accurate.

The Democrats' brief, along with a 14-page defense from Trump's lawyers, offer a preview of arguments both sides will likely make during the Senate trial, which begins February 9.

The House impeachment managers accuse Donald Trump of summoning a mob to Washington, D.C., on January 6, whipping the crowd "into a frenzy" and then aiming them "like a loaded cannon" at the U.S. Capitol, pinning the blame for the deadly violence that ensued directly on the former president.

Mr Trump is just the third president to have been impeached, is the first to be impeached twice and the first to face trial after leaving office.

For instance, CNN's chief White House correspondent, Kaitlan Collins, tweeted: "White House officials were shaken by Trump's reaction to a mob of his supporters descending on the Capitol today".

Failure to convict Trump "would embolden future leaders to attempt to retain power by any and all means - and would suggest that there is no line a president can not cross". But last week, 45 Republican senators signaled that they found the trial unconstitutional.

Here's a look at what the two sides say about Trump's impeachment.

"The present proceedings are moot and thus a nullity since the 45th president can not be removed from an office he no longer occupies", Trump lawyers Bruce Castor and David Schoen wrote in their own brief outlining the case for the defense.

Trump and Bowers initially agreed that the latter would be paid $250,000, which "delighted" the billionaire, according to the report.

Trump is facing impeachment for a second time over accusations he incited a deadly riot at the U.S. Capitol on January 6, 2021. Trump had urged his followers to attend, promising on Twitter it would be "wild". "You have to show strength, and you have to be strong, '" the House managers wrote.

"Finally, President Trump appeared behind a podium bearing the presidential seal".

The letter went on to say that many of its signatories went to school after the deadly Columbine High School massacre in Colorado in 1999 "and were trained to respond to active shooter situations in our classrooms".

Murkowski's analysis of Trump's lawlessness, and request for resignation showed that she is a courageous, principled Republican - her action does not make her a Democrat.

"There is no First Amendment defense to ignoring and violating your constitutional duty", Schiff told MSNBC.

"Indeed, the notion that a President can attack our democracy, provoke violence, and interfere with the Electoral College so long as he does so through statements advocating such lawlessness would have astonished the Framers", they say.

Additionally, they point to the "text and structure" of the Constitution as well as precedent to argue that the Senate can try a former president.

The House Democrats, in their pretrial brief, anticipated that post-presidency argument and rejected it. The Senate held the trial nonetheless.

Mr Trump's response took an unusual form, addressing the House's article of impeachment point by point.

That's the message from Trump's defense team, which used the word "denied" or "denies" a whopping 29 times in its 14-page brief.

House Democrats charge Donald Trump with "incitement of insurrection" for inspiring the MAGA mob, members of which carried his flag to the Capitol.

The pre-trial brief also noted how rioters stated publicly that they stormed the Capitol at Trump's urging.

"President Trump's conduct offends everything that the Constitution stands for", the Democratic impeachment managers wrote in an 80-page brief, noting that Mr Trump had begun voicing his intention to contest an election loss months before the November 3 election was held.

Trump was the most prominent leader who urged his supporters to "fight" and "stop the steal" for several weeks before the events of January 6, but he wasn't the only one.

Democrats also rejected the reasoning that Trump can not be tried once out of office.
