前白宫法律顾问唐·麦克甘星期五出现在众议院司法委员会面前，此前国会经过一年的努力，强制执行要求麦克甘就以下问题作证的传票与以下内容相关的事件前特别顾问罗伯特·穆勒的俄国调查。

上个月，在司法部、委员会和麦克甘就他的出庭达成初步协议后，他的证词被秘密获得。前总统唐纳德·特朗普不是协议的一方。

消息人士告诉美国广播公司新闻，特朗普通过他的前白宫副法律顾问帕特里克·菲尔宾(Patrick Philbin)向委员会明确表示，他不打算阻止麦加恩作证。另一位前白宫律师斯科特·加斯特(Scott Gast)将出席麦克甘的作证。

纽约司法部主席杰里·纳德勒(Jerry Nadler)在证词后的一份声明中表示，“麦克甘显然对特朗普总统拒绝听从他的法律建议感到不安，他一次又一次地为今天发生的几起令人不安的事件提供了新的线索。”

纳德勒没有说新的披露是什么，但补充说，一份完整的副本将“尽快”公布。

在当天早些时候的短暂休息中，纳德勒与记者进行了简短的交谈。当被问及在两年的战斗后让麦克甘接受质询意味着什么时，纳德勒说，“这证明了国会传票的权利。”

周五晚些时候，当被问及麦克甘是否合作时，纳德勒说，“我认为他是合作的，”几分钟后补充道，“我认为他有些困难，但当成绩单出来时，你会看到的。”

共和党众议员吉姆·乔丹(Jim Jordan)和马特·盖兹(Matt Gaetz)几个小时后对记者发表讲话，两人都批评众议院民主党人带回了他们所谓的旧调查，并表示采访没有透露任何新信息。

采访的条款规定，麦克甘不会与行政部门的员工讨论任何不在办公室的交流穆勒报告的公开部分。麦加恩还可以讨论穆勒的报告是否准确反映了麦加恩对调查人员的评论，以及他的陈述是否真实。

穆勒曾要求与麦克甘就前联邦调查局局长詹姆斯·科米被解雇的情况以及他参与前司法部长事件的报道进行谈话杰夫·赛辛斯俄罗斯调查的回避。

采访将在公开前七个日历日内由各方转录和审查。

在一个2019年6月独家采访特朗普在接受美国广播公司新闻频道(ABC News)记者乔治·斯特凡诺普洛斯(George Stephanopoulos)采访时表示，当麦克加恩告诉穆勒(Mueller)特朗普多次指示他让代理司法部长解除特别顾问的职务时，他“可能感到困惑”，因为他认为存在利益冲突。

“这个故事很简单，第一，我永远不会解雇穆勒。我从未建议解雇穆勒，”特朗普告诉斯特凡诺普洛斯。

当斯特凡诺普洛斯反驳并引用麦克加恩的证词时，特朗普表现得目中无人。

特朗普说:“我不在乎(麦克甘)说什么，没关系。”。"那是为了向每个人展示他是一个多么好的建议。"

2019年8月，众议院民主党人提起诉讼强制执行他们的传票要求麦克甘作证——这一举动使他们与白宫的争端急剧升级，因为他们将穆勒报告中一名关键证人的争执提交法院解决。

麦加恩与穆勒的调查人员呆了30多个小时，特朗普拒绝允许麦加恩向国会提供证词。

麦克甘的继任者、前白宫法律顾问帕特·西坡隆(Pat Cipollone)在给委员会的一封信中写道，“麦克甘绝对不会因担任总统高级顾问期间发生的事情而被迫接受国会证词。”

2019年11月，一名联邦地区法官裁定，麦克甘必须遵守国会传票。但随后，司法部对该裁决提出上诉，并于2020年2月在高等法院胜诉。

该案的听证会定于上月举行，但由于协议的原因没有举行。

Democrats say former Trump White House counsel Don McGahn 'shed new light on several troubling events' in long-awaited testimony

Former White House counsel Don McGahn appeared before the House Judiciary Committee Friday following a yearslong effort by Congress to enforce a subpoena demanding McGahn's testimony aboutevents related toformer special counsel Robert Mueller's Russia investigation.

His testimony, behind closed doors, was secured last month after the Justice Department, the committee and McGahn reached a tentative agreement on his appearance. Former PresidentDonald Trumpwas not a party to the agreement.

Trump, through his former deputy White House counsel Patrick Philbin, has made clear to the committee he doesn't intend to attempt to block McGahn from testifying, sources told ABC News. Scott Gast, another former White House lawyer, was to attend McGahn's testimony.

Judiciary Chairman Jerry Nadler, D-N.Y., said in a statement following the testimony that "McGahn was clearly distressed by President Trump’s refusal to follow his legal advice, again and again, and he shed new light on several troubling events today."

Nadler did not say what the new revelations were, but added a full transcript would be released "as soon as we can."

During a quick break earlier in the day, Nadler spoke briefly with reporters. Asked what it means to have McGahn available to question after the two-year battle, Nadler said, "It vindicates the congressional subpoena right."

Later Friday, when asked if McGahn seemed cooperative, Nadler said, "I think he’s cooperative," adding a few minutes after that, "I think he's being somewhat difficult, but you'll see that when the transcript comes out."

GOP Reps. Jim Jordan, R-Ohio and Matt Gaetz, R-Fla., spoke to reporters a few hours later, both men criticizing House Democrats for bringing back what they called an old investigation and saying the interview did not reveal any new information.

The terms of the interview state that McGahn will not discuss any communications he had with employees of the executive branch that aren't in thepublicly available portions of the Mueller report. McGahn can also discuss whether Mueller's report was an accurate reflection of McGahn's comments to investigators and whether his statements were truthful.

Mueller had requested to speak with McGahn about the circumstances surrounding former FBI Director James Comey's firing and his reported involvement in the events surrounding former Attorney GeneralJeff Sessions' recusal from the Russia investigation.

The interview will be transcribed and reviewed by all parties within seven calendar days before it is made public.

In anexclusive June 2019 interviewwith ABC News' George Stephanopoulos, Trump said McGahn "may have been confused" when he told Mueller that Trump instructed him multiple times to have the acting attorney general remove the special counsel because of perceived conflicts of interest.

"The story on that very simply, No. 1, I was never going to fire Mueller. I never suggested firing Mueller," Trump told Stephanopoulos.

When Stephanopoulos pushed back and referenced McGahn's testimony, Trump was defiant.

"I don't care what (McGahn) says, it doesn't matter," Trump said. "That was to show everyone what a good counsel he was."

In August 2019, House Democratsfiled a lawsuit to enforce their subpoenademanding McGahn testify -- a move that sharply escalated their dispute with the White House by sending the fight over a key witness in Mueller's report to court for a resolution.

McGahn spent more than 30 hours with Mueller's investigators and Trump had refused to allow McGahn to provide testimony to Congress.

McGahn's successor, former White House counsel Pat Cipollone wrote in a letter to the committee "that McGahn is absolutely immune from compelled congressional testimony with respect to matters occurring during his service as a senior adviser to the President."

In November 2019, a federal district judge ruled that McGahn must comply with a congressional subpoena. But then, the Justice Department appealed that ruling and in February 2020 won out in the higher court.

A hearing in the case was scheduled last month but did not occur due to the agreement.
