特勤局周四表示，在没有确定嫌疑人的情况下，已经结束了对可卡因最终出现在白宫的调查。
该机构的声明是在国会共和党人表示他们在一份机密文件中被告知后发表的特勤局简报对这起案件的调查在白宫西翼发现可卡因本月早些时候结束，但没有确定谁应该对此负责。
该机构在一份冗长的声明中说:“没有发现任何监控视频片段，可以为调查人员提供调查线索或任何其他手段，以确定谁可能在这一地区存放了发现的物质。”“没有物证，调查将无法从经过发现可卡因的门厅的数百人中挑出一个感兴趣的人。目前，由于缺乏物证，特勤局的调查已经结束。”
特勤局表示，联邦调查局犯罪实验室对包装进行了“先进的指纹和DNA分析”。
“调查包括对安全系统和协议的系统审查，”该机构声明说。“该审查包括在发现该物质前几天进行的回溯检查，并编制了可能进入发现该物质的区域的数百人的索引。这些行动的焦点开发了一个已知人员库，用于比较从联邦调查局对物质包装的分析中收集的法医证据。
“7月12日，特勤局收到了联邦调查局的实验室结果，没有发现潜在的指纹，也没有足够的DNA进行调查比较，”声明说。
在周四向众议院监督委员会(House Oversight Committee)的成员和工作人员进行闭门简报后，共和党人表示，他们认为这一进展是该机构的“失败”，并表示简报者表示调查即将结束。
“说他们不知道是谁，对我来说，有人应该因此丢掉工作。这东西是个垃圾桶。每个人都想挑挑拣拣。众议员蒂姆·伯切特说:“他们需要关闭整个系统，用软管冲洗，然后清理干净。”他补充说，特勤局在简报中告诉成员，袋子里装的可卡因不到一克。
成员们告诉记者，特勤局通知他们，在可卡因被发现的周末，他们将嫌疑人名单缩小到500人，并说这一群人包括工作人员和旅游的游客。西翼之旅只接受邀请。
成员们说，他们被告知墙上有182个储物柜，游客通常被告知在那里存放他们的电子产品和手机。他们说他们被告知可卡因是在50号储物柜里找到的。
共和党众议员劳伦·波伯特说那个柜子的钥匙不见了。
“没有合适的担保体系。没有储物柜的分配。这是我向特勤局提出的担忧之一。我们需要能够跟踪个人以及他们使用哪个储物柜，”她说。
众议院议长凯文·麦卡锡说:“任何围绕‘拜登公司’的事情都会受到与其他美国人不同的待遇，这必须停止。”
美国有线电视新闻网首次报道特勤局的结论是。
委员会主席詹姆斯·卡莫。他在7月7日写给特勤局局长金伯利·谢特尔的一封信中要求听取简报，并表示这一发现引发了对白宫安全的质疑。
“这一惊人的发展要求委员会评估白宫的安全措施，并确定谁的失误导致了大楼的疏散和非法物质的发现，”卡莫写道。
简报是在SCIF秘密进行的，这是一个用于处理机密信息的敏感信息设施。

自7月2日在白宫发现这种药物以来，特勤局一直在进行调查。到目前为止，没有人因为携带非法物质而受到指责。
当在一个工作区内发现一种粉末状的类似可卡因的物质时，白宫被短暂关闭，华盛顿消防部门被叫到现场。后来的测试证实这种物质是可卡因。
一位知情人士告诉ABC新闻，该药物位于西行政入口附近的一个小房间内，游客通常在这里放下他们的手机和其他物品。
作为调查的一部分，特勤局正在审查安全录像和访客记录。
白宫新闻秘书郭佳欣·让-皮埃尔说，在发现物质的周日以及前两天，有人参观了该地区，并形容该地区为“高度旅游”
美国总统乔·拜登、第一夫人吉尔·拜登和其他拜登家庭成员周五下午离开白宫，前往戴维营度过周末。
白宫拒绝对这一事件发表更多评论。在上周的一次新闻发布会上，让-皮埃尔被问了很多问题，但他只告诉记者，拜登已被告知此事，白宫有信心特勤局将“彻查此事”。
让-皮埃尔说:“我们与此事无关。”。“这是特勤局处理的事情。这是他们的协议。”
Secret Service ends investigation into cocaine found in White House without identifying a suspect
The Secret Service on Thursday said it had closed its investigation into how cocaine ended up at the White House without identifying a suspect.
The agency statement came after congressional Republicans said they were told in a classifiedSecret Service briefingthat the investigation into thecocaine found in the White House West Wingearlier this month was concluding without a determination of who was responsible.
"There was no surveillance video footage found that provided investigative leads or any other means for investigators to identify who may have deposited the found substance in this area," the agency said in a lengthy statement. "Without physical evidence, the investigation will not be able to single out a person of interest from the hundreds of individuals who passed through the vestibule where the cocaine was discovered. At this time, the Secret Service's investigation is closed due to a lack of physical evidence."
The Secret Service said the packaging was "subjected to advanced fingerprint and DNA analysis," by the FBI crime lab.
"The investigation included a methodical review of security systems and protocols," the agency statement said. "This review included a backwards examination that spanned several days prior to the discovery of the substance and developed an index of several hundred individuals who may have accessed the area where the substance was found. The focal point of these actions developed a pool of known persons for comparison of forensic evidence gleaned from the FBI's analysis of the substance's packaging.
"On July 12, the Secret Service received the FBI's laboratory results, which did not develop latent fingerprints and insufficient DNA was present for investigative comparisons," the statement said.
Following Thursday's closed-door briefing to members and staff of the House Oversight Committee, Republicans said they viewed the development as a "failure" of the agency and said the briefers said the investigation was concluding.
"And to say that they don't know who it is, to me, somebody should lose their job over this. This thing's a trash can. Everybody wants to pick and choose. They need to shut the whole thing down put the garden hose to it and clean it out," Rep. Tim Burchett said, adding that the Secret Service told members in the briefing the bag contained less than a gram of cocaine.
Members told reporters the Secret Service informed them they narrowed down the list of suspects to 500 people during the weekend that cocaine was found and said that group included a mix of staffers and visitors who were on a tour. West Wing tours are invitation only.
Members said they were told there are 182 lockers on the wall where visitors are typically told to store their electronics and cell phones. They said they were told the cocaine was found in locker 50.
GOP Rep. Lauren Boebert said the key to that locker is missing.
"There's no collateral system in place. There's no assigning of the lockers. And this was one of the concerns I raised to Secret Service. We need to be able to track individuals and which locker they are using," she said.
"Anything revolving around "Biden Inc" gets treated different than any other American and that's got to stop," House Speaker Kevin McCarthy said.
CNNfirst reportedthe Secret Service's conclusion.
Committee chair James Comer, R-Ky., said the discovery raises questions about security at the White House when he requested the briefing in a letter sent to Secret Service Director Kimberly Cheatle on July 7.
"This alarming development requires the Committee to assess White House security practices and determine whose failures led to an evacuation of the building and finding of the illegal substance," Comer wrote.
The briefing took place behind closed doors in a SCIF -- a sensitive compartmented information facility used to handled classified information.
The Secret Service has been investigating since the drug was found at the White House complex on July 2. So far, no one has been blamed for bringing in the illegal substance.
The White House was briefly shut down and the D.C. Fire Department was called to the scene when a powdery, cocaine-like substance was found inside a work area. Testing later confirmed the substance was cocaine.
A source familiar with the matter told ABC News the drug was located inside a cubby near the West Executive entrance where visitors typically drop off their cell phones and other belongings.
As part of the probe, the Secret Service was reviewing the security footage and visitor logs.
White House press secretary Karine Jean-Pierre said there had been tours conducted the Sunday the substance was found as well as the two days prior, and described the area as "highly traveled."
President Joe Biden, first lady Jill Biden and other Biden family members left the White House Friday afternoon to spend the weekend at Camp David.
The White House has declined to extensively comment on the incident. Jean-Pierre was peppered with questions during a press briefing last week, but only told reporters that Biden had been briefed on the matter and the White House was confident the Secret Service would "get to the bottom of this."
"We are not involved in this," Jean-Pierre said. "This is something that the Secret Service handles. It's under their protocol."
