国土安全部内部最高网络安全机构的领导人，他一再谴责总统的声明唐纳德·特朗普总统周二在推特上宣布，他关于广泛选民欺诈的竞选活动现已被解雇。

一位知情人士上周告诉美国广播公司新闻，网络安全和基础设施安全局局长克里斯托弗·克雷布斯(Christopher Krebs)预计将被解雇。

总统批评了克雷布斯机构发表的声明没有欺诈的证据在2020年的选举中。特朗普在宣布解雇克雷布斯时，重申了此前对选举中欺诈的指控。

特朗普在推特上写道:“克里斯·克雷布斯(Chris Krebs)最近关于2020年选举安全的声明非常不准确，因为存在大量不当行为和欺诈行为——包括死人投票、投票观察者不被允许进入投票地点、将选票从特朗普换成拜登的投票机出现‘故障’、投票延迟等，”特朗普在推特上没有证据的情况下写道。"因此，克里斯·克雷布斯被解除网络安全和基础设施安全局局长的职务，立即生效."

这条推特立即遭到推特的警告，称这些说法有争议。

在推特上，克雷布斯在被解雇后写道，“很荣幸为您服务。我们做对了。”

克雷布斯是CISA的第一任董事，自2018年11月起任职。

CISA在上周四的一份声明中说，“没有证据表明任何投票系统删除或丢失了选票，改变了选票，或以任何方式受到损害。”

CISA负责确保2020年选举的安全，并一直在其网站上披露其所谓的与选举有关的“谣言”，包括特朗普及其盟友传播的谣言。

CISA的“谣言控制”网站被拆穿从投票软件中的软件故障到死人投票。

选举基础设施政府协调委员会执行委员会的成员说:“虽然我们知道有许多关于我们选举过程的毫无根据的说法和错误信息的机会，但我们可以向你保证，我们对我们选举的安全和完整性有最大的信心，你也应该这样做。”。"当你有问题时，求助于选举官员，因为他们在管理选举时是值得信任的声音."

这声明接着说，“11月3日的选举是美国历史上最安全的一次。”

参议院情报委员会(Senate Intelligence Committee)成员、缅因州参议员安格斯·金(Angus King)在推特上表示，特朗普通过终止克雷布斯(Krebs)正在“给美国人造成严重损害”。

金写道:“如果说这个不公正的决定有什么好的一面，那就是:我希望当选总统拜登将认识到克里斯的贡献，并在拜登政府规划这个至关重要的机构的未来时与他协商。”

其他人对克雷布斯的解雇表示愤慨，并对这位前导演表示支持。

乔·拜登的竞选发言人迈克尔·格文说:“克里斯·克莱伯斯为保护我们的选举所做的贡献应该受到表扬，而不是因为他说了实话而被解雇。”。“政府内部以及全国各地的两党选举官员已经明确表示，唐纳德·特朗普关于普遍选民欺诈的说法是完全错误的，特朗普尴尬地拒绝接受现实，暴露了他的抨击是多么毫无根据和绝望。”

内布拉斯加州共和党参议员本·萨塞(Ben Sasse)表示，这次开火是不劳而获的。

萨斯在一份声明中说:“克里斯·克雷布斯做得很好——全国的州选举官员都会告诉你——他显然不应该被解雇。”“我特别感谢他在网络日光浴室委员会帮助国家为未来的战争做准备的工作。”

前奥巴马网络安全委员会成员基尔斯顿·托德(Kiersten Todt)在一份声明中表示:“克里斯·克雷布斯(Chris Krebs)作为CISA的首任主任，在执掌该公司期间做了大量工作。”。“人们忘记了四年前DHS的名声并不太好。克雷布斯通过他在CISA的领导，为该机构的工作带来了可信度，并在四年时间里致力于为2020年的安全选举而努力

克雷布斯预计上周被解雇的第一个消息是由路透社。

另一位知情人士告诉美国广播公司新闻，周四，CISA的另外两名员工——CISA网络安全助理主任布莱恩·韦尔(Bryan Ware)和美国国土安全部国际事务助理部长瓦莱丽·博伊德(Valerie Boyd)——被要求辞职，但他们的电子邮件截至周五似乎仍处于活跃状态。两位官员都没有回应美国广播公司新闻的置评请求。

上周，CISA没有回复置评请求，当被问及克雷布斯是否会被解雇，威尔和博伊德是否会被要求辞职，或者白宫是否参与其中时，白宫拒绝回应。

上周四，在新闻报道他预计将被解雇后，克雷布斯在推特上亲自向美国人保证选举是安全的。

他在推特上写道:“美国，我们对你投票的安全性有信心，你也应该有信心。”。

DHS cybersecurity head Christopher Krebs fired by President Trump after he disputes fraud claims

The leader of the top cybersecurity agency inside the Department of Homeland Security, who has repeatedly rebuked claims made by PresidentDonald Trumpand his campaign about widespread voter fraud, has now been fired, the president Tuesday announced on Twitter.

Christopher Krebs, the director of the Cybersecurity and Infrastructure Security Agency, had expected to be fired, a source with knowledge of the situation told ABC News last week.

The president criticized a statement given by Krebs' agency saying there wasno evidence of fraudduring the 2020 election. In announcing Krebs' firing, Trump repeated previously debunked claims of fraud in the election.

"The recent statement by Chris Krebs on the security of the 2020 Election was highly inaccurate, in that there were massive improprieties and fraud -- including dead people voting, Poll Watchers not allowed into polling locations, 'glitches' in the voting machines which changed votes from Trump to Biden, late voting, and many more," Trump wrote without evidence on Twitter. "Therefore, effective immediately, Chris Krebs has been terminated as Director of the Cybersecurity and Infrastructure Security Agency."

The tweet was immediately slapped with a warning from Twitter that the claims were disputed.

On Twitter, Krebs wrote following his firing, "Honored to serve. We did it right."

Krebs was the first director of the CISA and had served since November 2018.

The CISA said in a statement last Thursday, "There is no evidence that any voting system deleted or lost votes, changed votes, or was in any way compromised."

CISA is responsible for securing the 2020 elections and has been exposing what it calls election-related "rumors" on its website -- including those spread by Trump and his allies.

CISA's "Rumor Control" site hasdebunkedeverything from software glitches in voting software to votes being cast by dead people.

"While we know there are many unfounded claims and opportunities for misinformation about the process of our elections, we can assure you we have the utmost confidence in the security and integrity of our elections, and you should too," the members of Election Infrastructure Government Coordinating Council Executive Committee said. "When you have questions, turn to elections officials as trusted voices as they administer elections."

Thestatementgoes on to say that "The November 3rd election was the most secure in American history."

Sen. Angus King, I-Maine, who sits on the Senate Intelligence Committee, tweeted Trump is "inflicting severe damage" on Americans by terminating Krebs.

"If there's any silver lining in this unjust decision, it's this: I hope that President-elect Biden will recognize Chris's contribution, and consult with him as the Biden administration charts the future of this critically important agency," King wrote.

Others echoed the outrage at Krebs' firing and added voices of support to the former director.

"Chris Krebs should be commended for his service in protecting our elections, not fired for telling the truth," Joe Biden's campaign spokesperson Michael Gwin said. "Bipartisan election officials in the administration itself -- and around the country -- have made clear that Donald Trump's claims of widespread voter fraud are categorically false and Trump's embarrassing refusal to accept that reality lays bare how baseless and desperate his flailing is."

Nebraska Sen. Ben Sasse, a Republican, said the firing was unearned.

"Chris Krebs did a really good job -- as state election officials all across the nation will tell you -- and he obviously should not be fired," Sasse said in a statement. "I'm particularly grateful for the work he did on the Cyber Solarium Commission to help the nation prepare for the future of war."

"Chris Krebs did a tremendous job at the helm of CISA, as its first director," said Kiersten Todt, a former Obama Cybersecurity Commission member, in a statement. "People forget that the reputation of DHS was not too strong four years ago. Krebs, through his leadership at CISA, gave credibility to the work of this agency, and was committed for four years to working toward a safe and secure election in 2020."

The first news of Krebs' expected firing last week were reported byReuters.

Two other CISA staffers, Bryan Ware, assistant director for cybersecurity for CISA, and Valerie Boyd, assistant secretary for international affairs at U.S. Department of Homeland Security, were asked to resign Thursday, a separate source familiar with the matter also told ABC News, but their emails appeared active as of Friday. Neither official responded to an ABC News request for comment.

Last week, CISA did not returned a request for comment, and the White House declined to respond when asked whether Krebs would be fired, whether Ware and Boyd were asked to resign, or whether the White House was involved.

Last Thursday, following news reports he expected to be fired, Krebs took to Twitter to personally assure Americans the election was secure.

"America, we have confidence in the security of your vote, you should, too," he tweeted.
