首席大法官约翰·罗伯茨在参议院弹劾唐纳德·特朗普总统的审判中告诫双方，敦促在场的人“记住他们在哪里”
在众议院经理兼众议院司法委员会主席、众议员杰瑞·纳德勒(纽约民主党)与总统顾问帕特·西波尔隆和杰伊·塞库洛之间激烈的来回争吵后，罗伯茨进行了干预。
纳德勒指责共和党占多数的参议院投票反对在审判开始时听取新的关键证人的证词，特别是来自特朗普的前国家安全顾问约翰·博尔顿称之为“背信弃义”
西波隆告诉纳德勒，他应该道歉，并抨击国会议员的“虚假指控”，而塞库洛指责民主党粉碎宪法。
罗伯茨在周二晚交易结束后表示:“我认为，在这一点上，我应该平等地告诫众议院经理和总统顾问，记住他们是在向世界上最大的审议机构发表讲话。”。
“它赢得这一头衔的一个原因是，它的成员避免以不利于公民对话的方式和语言发言。
“在1905年的斯温审判中，一名参议员反对，因为其中一名管理人员使用了派迪福格这个词，主持官员说这个词不应该使用。
“我不认为我们需要追求这么高的标准，但我确实认为那些在参议院发言的人应该记得他们在哪里。”
民主党试图通过一系列修正案获得参议院的支持，让博尔顿证明他对所谓的乌克兰计划的了解，该计划是特朗普下台的核心。
特朗普否认有任何不当行为，他被弹劾了两篇文章:滥用权力和阻挠国会。众议院指控特朗普在2020年选举中寻求乌克兰的干预，以利于他的竞选，然后阻碍调查工作。
纳德勒在参议院表示，参议员不会投票让博尔顿或其他证人出庭作证，美国人应该感到“震惊”。
“总统正在参议院接受审判，但是在美国人民的眼里，参议院正在接受审判。你会投票允许所有相关证据在这里出示，还是会违背你作为一个公正陪审团的承诺？”纳德勒说。
“你能把博尔顿大使带到这里来吗？你能允许我们向你展示总统不当行为的全部记录吗？还是你会选择成为总统掩盖真相的同谋？
“到目前为止，我很遗憾地说，我看到许多参议员投票支持掩盖真相，投票否认证人——显然这是一个绝对站不住脚的投票。背信弃义的投票。投票反对对不利于总统的证据进行诚实的考虑。投票反对诚实的审判，投票反对美国。”
白宫法律顾问西波隆站出来说，纳德勒对特朗普、参议员和总统法律顾问提出了“虚假指控”。
“纳德勒先生，唯一应该感到尴尬的是你对这个机构的讲话方式。这是美国参议院。你不是这里的负责人，”西波隆说。
“美国人民支付他们的工资，他们是来拿走他们的选票的。他们是来剥夺他们的声音的。他们来到这里，袭击了我们政府的每一个机构……是时候让这次权力之旅着陆了。
“这是一场闹剧，应该结束。纳德勒先生，你应该向美国总统和他的家人道歉。你应该向参议院道歉。但最重要的是，你应该向美国人民道歉。”
总统的律师塞库洛说，纳德勒“在参议院粉碎了宪法……我来告诉你什么是背信弃义的，到参议院说‘行政特权和其他废话’"
会议于周三凌晨结束。共和党人投票决定先听取辩论，然后在审判中决定传唤证人。
2020年1月21日，在DC华盛顿美国国会大厦参议院，最高法院首席法官约翰·罗伯茨主持了对美国总统唐纳德·特朗普的弹劾程序。
CHIEF JUSTICE ADMONISHES TRUMP'S COUNSEL AND HOUSE MANAGERS AMID ACCUSATIONS OF TREACHERY AND SHREDDING THE CONSTITUTION
Chief Justice John Roberts admonished both sides at the Senate impeachment trial of President Donald Trump, urging those presenting to "remember where they are."
Roberts intervened after a testy back-and-forth between Congressman Jerry Nadler (D-NY), a House manager and chairman of the House Judiciary Committee, and the president's counsels Pat Cipollone and Jay Sekulow.
Nadler scolded the GOP-majority Senate for voting against hearing new key witnesses at the outset of the trial, in particular testimony from Trump's former national security adviser John Bolton, calling it "treacherous."
Cipollone told Nadler he owed an apology and hit out at the congressman's "false allegations," while Sekulow accused the Democrat of shredding the constitution.
"I think it is appropriate at this point for me to admonish both the House managers and the president's counsel in equal terms to remember that they are addressing the world's greatest deliberative body," Roberts said after the exchange ended on Tuesday night.
"One reason it has earned that title is because its members avoid speaking in a manner and using language that is not conducive to civil discourse.
"In the 1905 Swain trial, a Senator objected when one of the managers used the word pettifoggery and the presiding officer said the word ought not to have been used.
"I don't think we need to aspire to that high a standard, but I do think those addressing the Senate should remember where they are."
Democrats attempted through a series of amendments to secure the Senate's backing for bringing Bolton to testify about his knowledge of the alleged Ukraine scheme at the center of the case for removing Trump from office.
Trump, who denies any wrongdoing, is impeached with two articles: Abuse of power and obstruction of Congress. The House accuses Trump of soliciting Ukraine's interference in the 2020 election to benefit his campaign and then obstructing efforts to investigate.
Nadler said on the Senate floor that Americans should be "shocked" that senators would not vote to bring Bolton or other witnesses to testify.
"The president is on trial in the Senate, but the Senate is on trial in the eyes of the American people. Will you vote to allow all of the relevant evidence to be presented here or will you betray your pledge to be an impartial jury?" Nadler said.
"Will you bring Ambassador Bolton here? Will you permit us to present you with the entire record of the president's misconduct? Or will you instead choose to be complicit in the president's cover-up?
"So far, I'm sad to say, I see a lot of senators voting for a cover-up, voting to deny witnesses—an absolutely indefensible vote, obviously. A treacherous vote. A vote against an honest consideration of the evidence against the president. A vote against an honest trial, a vote against the United States."
Cipollone, the White House counsel, stepped up and said Nadler was making "false allegations" against Trump, the senators and the president's counsel.
"The only one who should be embarrassed, Mr. Nadler, is you for the way you've addressed this body. This is the United States Senate. You're not in charge here," Cipollone said.
"The American people pay their salaries and they are here to take away their vote. They're here to take away their voice. They've come here and they've attacked every institution of our government…It's about time we bring this power trip in for a landing.
"It is a farce and it should end. Mr. Nadler, you owe an apology to the president of the United States and his family. You owe an apology to the Senate. But most of all, you owe an apology to the American people."
Sekulow, a lawyer for the president, said Nadler had "shred the constitution on the floor of the Senate…I'll tell you what's treacherous, come to the floor of the Senate and say 'executive privilege and other nonsense.'"
The session ended in the early hours of Wednesday morning. Republicans voted to hear the arguments first before deciding on calling witnesses later on in the trial.
