Former President Donald Trump's historic second impeachment trial ended with a 57-43 vote to acquit in the Senate. He faced a single charge of incitement of insurrection over his actions leading up to the Jan. 6 riot at the U.S. Capitol.
The House managers have finished laying out their case against Trump and the Senate has adjourned for the day.
The trial will resume at noon on Friday, when Trump's legal team will deliver their argument.
Lead House manager Rep. Jamie Raskin, D-Md., said the managers are wrapping up their opening arguments in Trump's second impeachment trial.
"We think we have been able to tell you everything we need to say," Raskin said, noting that the managers are 5-6 hours under the time allotted to them.

As House managers begin to wrap up their opening arguments, House manager Rep. Joe Neguse, D-Colo., reviewed the evidence they presented throughout their opening argument.
"He directed them here to Congress. He quite literally, at one part of that speech, pointed at us. He told them to fight like hell and if you don't fight like hell, you're not going to have a country anymore. And here's the thing, that wasn't metaphorical, it wasn't rhetorical," Neguse said. "He'd already made it perfectly clear that when he said 'fight,' he meant it."
The House managers focused on Trump's remarks at the rally shortly before the attack on the Capitol, again showing videos of what he told the crowd, saying that he 'knew' they would act on violence.
"He was told by law enforcement and all over the news that these people were armed and ready for real violence. He knew it, I mean, he knew it perfectly well that he had created this powder keg at his rally. He knew just how combustible that situation was. He knew (the) people before him who had prepared, who are armed and armored. He knew they would jump to violence at any signal, at any sign, from him that he needed them to fight, that he needed them to stop the steal," Neguse said. "And we all know what happened next."
Neguse also played several recordings of Republicans, both during and after the attack on the Capitol, in which they directly called on Trump to put a stop to the violence or blamed him for it -- in an attempt to illustrate that some Republicans have publicly and directly already tied Trump to the riot.
"We humbly, humbly, ask you to convict President Trump for the crime for which he is overwhelmingly guilty of," Neguse said. "Because if you don't, if we pretend this didn't happen, or worse, if we let it go unanswered, who's to say it won't happen again?"
House Speaker Nancy Pelosi said earlier Thursday that she is planning to introduce legislation that would award the Capitol Police and law enforcement personnel who protected the Capitol on Jan. 6 with the Congressional Gold Medal.
"The service of the Capitol Police force that day brings honor to our Democracy, and their accepting this Gold Medal will bring luster to this award," she wrote in a letter to her colleagues.
The Congressional Gold Medal is the highest honor that the lawmakers can bestow.
"We must never forget the sacrifice of Officer Brian Sicknick, Officer Howard Liebengood, MPD Officer Jeffrey Smith and the more than 140 law enforcement officers who sustained physical injuries, or the courage of heroes such as Officer Eugene Goodman," Pelosi wrote in her letter.
She also asked her fellow members to co-sponsor the legislation.
In response, acting U.S. Capitol Police Chief Yogananda Pittman said in a statement that the department is "humbled and appreciative."
"To have our police officers' bravery acknowledged at a time when they're experiencing tremendous emotions and exhaustion is a gift. We have too many heroes to count and we are humbled Congress may recognize them in this way," Pittman said in the statement. "From the cards and letters of support we've received from around this great country to this incredible award, we are deeply humbled and appreciative."
Pittman also acknowledged the Metropolitan Police Department officers who supported Capitol Police on Jan 6.
