Democrats making the case that Donald Trump should be convicted of inciting the deadly siege at the U.S. Capitol will focus on Thursday on the damage wrought in the rampage and the former president's role in inflaming the rioters.
The House of Representatives has charged Trump, a Republican, with inciting an insurrection by exhorting thousands of supporters to march on the Capitol on Jan. 6, the day Congress gathered to certify Democrat Joe Biden's election win.
The House managers who are prosecuting the case in the U.S. Senate spent much of Wednesday recounting the events that led to the riot and highlighting the threat to Mike Pence, Trump's vice president.
On Thursday, they planned to illustrate the "terrible toll" of the riot and Trump's "role in assembling, inciting and inflaming the insurrectionists," a House aide said.
There also will be a focus on Trump's "lack of remorse" during and following the siege, "which is an element in the impeachment calculus," the aide said.
While some Republican senators have said that the House Democrats are presenting their arguments against Trump well, many remained unconvinced Trump should be convicted.
Republican Senator Marco Rubio told Fox News that while the Jan. 6 attack was "horrifying," impeachment was not appropriate given that Trump was no longer in office.
A senior Senate Republican aide said "the cake is baked," with most of the party's 50 senators opposing conviction.
Senators on Wednesday were shown searing security footage of the pro-Trump mob stalking the Capitol hallways chanting "Hang Mike Pence!" and searching for Democratic House Speaker Nancy Pelosi.
Previously unseen videos showed the view from inside the Capitol as rioters smashed windows and fought with police, coming within 100 feet (30m) of the room where Pence was sheltering with his family. The mob had set up a gallows outside.
The footage, which also included body-camera views of brutal attacks on Capitol police, showed Pence and lawmakers being hustled to safety steps ahead of an advancing mob. The attack on the Capitol resulted in the deaths of five people, including police officer Brian Sicknick.
Trump had repeatedly said Pence had the power to stop the certification of the election results, even though he did not.
"The mob was looking for Vice President Pence," Representative Stacey Plaskett said, narrating footage that showed the crowd threatening Pence and searching for Pelosi.
"President Trump put a target on their backs and then his mob broke into the Capitol to hunt them down," she said.
Democratic Representative Joaquin Castro pointed out that during the rampage, Trump tweeted that Pence "didn't have the courage to do what should have been done." A video showed rioters spreading word of Trump's tweet to one another on bullhorns.
House managers said Trump had planted the seeds for the riot by encouraging violence and making false claims the election was stolen long before Jan. 6. They also said he did little to put an end to the violence as it spiraled out of control, despite pleas from many Republicans to ask his supporters to stop.
Democrats face a difficult task in securing a Senate conviction and barring Trump from ever again seeking public office. A two-thirds majority in the Senate must vote to convict, which means at least 17 Republicans would have to defy Trump and his continued popularity among Republican voters.
On Tuesday, the Senate voted largely along party lines that the impeachment trial could move ahead even though Trump's term ended on Jan. 20. Six of 50 Republican senators broke with their caucus to side with Democrats.
"I am holding out hope that the forcefulness of this argument will still sway some. I believe there are more Republicans that are open to conviction than is publicly clear at this point," said Democratic Senator Chris Coons.
Trump's lawyers, who will have 16 hours to deliver their defense, said the video and other evidence presented by Democrats had not made the case for his culpability.
"We know a mob breached the Capitol and wreaked havoc in the building. I'm waiting for them to connect that up to President Trump and so far that hasn't happened," said Trump lawyer Bruce Castor.
The Senate trial could conclude as early as Saturday or Sunday, according to a senior Senate aide.
Trump is the first U.S. president to be impeached twice and the first to face trial after leaving office. His first impeachment trial, which stemmed from his efforts to pressure Ukraine to investigate Biden, ended in an acquittal a year ago in what was then a Republican-controlled Senate.
