Given we’re hearing so many of these names again on the Senate floor during this impeachment trial, here's a primer on where key players in the saga are now:

Rudy Giuliani: While not a formal part of the president’s impeachment defense team, he’s still part of the broader outside team and appeared on Fox this week to defend the president and discuss the Parnas situation.

Fiona Hill: Her representative says she has returned to the Brookings Institution, where she was a senior fellow on Europe prior to joining the Trump administration.

Yuri Lutsenko: He’s no longer a Ukrainian government official and as of October, had relocated to London, saying he wanted to study English there. In October, Ukraine’s State Bureau of Investigations opened a criminal investigation into Lutsenko on allegations of abuse of power. Like Viktor Shokin (see below), he’s continued to cooperate with Giuliani, giving him a new interview in December while Giuliani was in Europe. 

Tim Morrison: He is now a senior fellow at the Hudson Institute after leaving his National Security Council position this fall. 

Lt. Col. Alexander Vindman: We believe Vindman remains detailed to the National Security Council from the Department of Defense, although Ambassador Robert O’Brien suggested in November he would be rotated out at some point. Vindman’s attorney previously has said publicly that he is on that detail until July. 

Lev Parnas: He’s under federal indictment in the Southern District of New York on campaign finance charges and on house arrest in Miami (but has received special dispensation to travel for those media interviews he’s been conducting and to meet with his attorneys in New York).

Viktor Shokin: He retired as a prosecutor and is living in Ukraine. Giuliani said in December that Shokin was “not healthy” and had difficulty traveling. He has also been cooperating with Giuliani, giving him an interview in December in Europe.

Gordon Sondland: He remains U.S. ambassador to the E.U., where — per The Washington Post — he's trying to lay low and go about his usual business in Brussels. 

Bill Taylor: He left his position as the top diplomat in Ukraine on Jan. 1 as well as the State Department. 

Kurt Volker: He resigned under pressure during the impeachment saga from his post running the McCain Institute, but he’s remained as senior international advisor at BGR Group, a D.C. public affairs and lobbying shop.

Jennifer Williams: We believe Williams remains on that detail to the vice president’s office from the State Department, a rotation that began April 1. The vice president’s office didn’t immediately respond to a request for comment on her current status.

Marie Yovanovitch: The former U.S. ambassador to Ukraine is a senior State Department fellow at Georgetown’s Walsh School of Foreign Service in the Institute for the Study of Diplomacy, but is not teaching classes this semester.  

Purpura presented a key part of Trump's defense early on Saturday, saying Zelenskiy and his top aides said publicly that the Ukrainian president felt no pressure in his July 25 phone call with the president.

Purpura said such an assertion from Ukraine amounts to case closed, saying a judge would "toss" such a case based on that evidence. He added that the Democrats are essentially calling these Ukrainian officials untruthful.

Of course, Democrats have argued that Ukrainian officials had to say such publicly, because if they said Trump pressured them, it would almost certainly result in Ukraine facing negative consequences.

"They will also make the argument Ukraine thinks the call was perfect and they said there was no pressure," Schiff said in his closing argument. "That really means Ukraine knows it's beholden to us for aid. Ukraine still hasn't gotten into the door of the White House."

"Ukraine knows if they acknowledge they were shaken down by the president of the United States, the president of the United States will make them pay," he continued. "So when you hear them say Ukraine felt no pressure that's because [Zelenskiy] doesn't want to call him a bad name. You well know why because they need America. The framers did not expect you to leave your common sense at the door."

Lev Parnas's attorney Joseph Bondy told MSNBC's Rachel Maddow that he has turned over a 2018 recording of President Donald Trump appearing to order the firing of former Ukraine Amb. Marie Yovanovitch to the House Intelligence Committee as of Friday evening. 

Bondy said that he turned over the tape to the panel, which took the lead on the impeachment inquiry, and wants them to make it public because it could help his client's case. 

"I hope they'll make it public," he said. "I think it's of critical importance that we hear the evidence. I think that's the best was we have to ensure our chances of having a fair trial, real trial if you will." 

MSNBC has heard portions of the recording, which was first reported by ABC News. 

Bondy said that he and his client are not the source of ABC's story.

During Schiff's closing remarks the chamber was almost entirely full expect for three empty seats on the Republican side. The room was very engaged with Schiff's remarks— many never breaking their gaze. 

When Schiff mentioned the CBS report that said Republican senators were told their heads "will be on a pike" if they vote against Trump, Collins said "that’s not true" fairly loudly multiple times and shook her head vigorously. 

The floor was almost completely captivated by Schiff, especially during the emotional family stories, with no one taking notes or reading.

Later, Sen. Joni Ernst, R-Iowa, called the story "baloney."

"It's hard to keep an open mind when there's so much baloney being thrown at you," she said.

Schiff concluded Democrats' opening arguments on Friday night, appealing to the senators' faith in American ideals and urging them to consider this trial's place in history and the world.

Schiff said he believed this trial was "a moment when our democracy was gravely threatened and not from without from within. Russia too has a constitution. It’s not a bad constitution, it’s just a meaningless one."

He argued that America is a beacon of democracy and fairness around the world while suggesting the outcome of this trial could threaten it.

"From all over the world, they look to us — and increasingly, they don't recognize what they see," Schiff said. "Americans get a fair trial — and so I ask you, I implore you. Give America a fair trial. Give America a fair trial. She’s worth it."

A number of senators spoke to reporters during the dinner break about what they’ve witnessed so far today. Some Republican senators took aim at the House managers— in particular, Nadler's "dictator" comment seemed to strike a nerve.

"Nadler's disposition and tone throughout this entire process, I don't think, it doesn't reflect well on the House process," said John Thune, R-S.D. "I mean I think it's been very partisan and he's got a very partisan tone which is carried over into the, into the Senate, and so it's, you know, it probably doesn't matter to that many people in this room, because everybody kind of knows what they're dealing with there but I don't think it probably helps them with the American public."

"I feel like I'm, like, the prop in the longest political commercial that's ever been produced," said GOP Sen. Roy Blunt of Missouri. "Did y'all get that?”

Sen. Richard Blumenthal, D-Conn, said that his Republican colleagues will "be haunted" if they keep "refusing to see the facts."

He said they "have to understand the truth will come out sooner than they think, and they're gonna be haunted by it, because they'll have to justify refusing to see the facts that are fully available to them and witnesses and documents and that's going to be a pretty tough burden for them to carry into this election."

Schiff attempted to preview some of Trump’s potential defenses, seeking to debunk the various arguments as he went along. 

"I expect you’ll hear the argument Obama did it! Obama did it. Now that may take several different forms, but the form of Obama did it I’m referring to is Obama also held aid. I think that argument is an insult to our intelligence," Schiff said, pointing to how then-President Obama withheld aid during Egypt’s revolution.

"You will hear the call was perfect, you’ll hear the call was perfect. Now I suspect the reason they will make the argument the call was perfect is that because the president insists they do," he said. "I don’t think they really want to have to make that argument — you wouldn’t either. But they have a client to represent so they will make the argument the call was perfect."

He continued: "And they will also make the argument Ukraine thinks the call was perfect, Ukraine says there was no pressure. What that really means is Ukraine wants a future. Ukraine knows it’s still beholden to us for aid. Ukraine still hasn’t gotten through the door of the White House. Ukraine knows that if they acknowledge that they were shaken down by the President of the United States, the President of the United States will make them pay."

Schiff, as part of his closing remarks, said that Trump and his allies haven't seemed particularly invested in answering the gravity of the charges the House has laid out against the president — choosing instead to attack the process and the Democratic House managers, including himself. 

He then recalled a moment that Trump revisits often — when he parodied Trump's phone call with Ukraine's president while chairing a hearing of the House Intelligence Committee last September. 

"I discovered something very significant by mocking the president and that is for a man who loves to mock others, he does not like to be mocked. As it turns out, he's got a pretty thin skin. Who would have thought it?” Schiff said. “Never mind that I said I wasn't using his words before I said, and I wasn't using his words after I said it, and I said I was making a parody of his words — 'It's an outrage! He mocked the president, that Schiff! Terrible!'"

Trump has said Schiff should resign and be investigated for his mocking interpretation of that July phone call, in which Trump asked a foreign leader to look into the Bidens, as well as a conspiracy involving the 2016 election.

"He is a sick man!" Trump tweeted last September.  

Schiff read through the articles of impeachment on Friday night, arguing that the managers had proved each element with the refrain 'that has been proved.'

“President Trump solicited the interference of a foreign government in the 2020 election," he began. "That has been proved."

Looks like tonight could be an early night for impeachment watchers, as manager Schiff says he’ll be the last speaker tonight.

"I'm tired! I don't know about you but I'm exhausted,” he said.

Schiff joked that he was hoping to keep things short tonight, the conclusion of House Democrats' case against the president.

"To be immortal, you don’t need to be eternal."

A Democratic staffer working on the impeachment trial lays their case out as follows:

• Democrats made an overwhelming, compelling and airtight case — the evidence is absolutely incriminating, the facts are uncontested.

• It’s clear that the President is an ongoing threat to our national security and the upcoming elections. That’s why he must be removed.

• House Managers made a direct appeal to the Senators to consider the lasting impact of the President’s actions on our democracy, constitutional framework and Congress’ ability to exercise oversight of the executive branch. 

• Americans overwhelmingly want a fair trial. All trials include documents and witnesses – in this case, the hundreds and hundreds of pages of documents and dozen witnesses the President has blocked.
