据知情人士透露，这批可卡因是在白宫底层靠近西行政入口的地方发现的，访客通常会被告知在那里放下手机。
一些游客，但不是普通公众，可以参观西翼的一部分，参观通常在周末进行。
白宫新闻秘书郭佳欣·让-皮埃尔周三证实，上周五、周六和周日都有旅行团。
乔·拜登总统及其家人当时正在戴维营。
让-皮埃尔周三告诉记者，“总统认为彻查可卡因如何出现在白宫非常重要”，但她将几乎所有问题推迟到特勤局继续调查。
“这个被发现的地方是一个人流量很大的地方，许多白宫西翼，我应该更具体地说，西翼的游客都经过这个特定的区域。我只是没有更多的东西可以分享，”她说。
“特勤局正在调查此事。这是他们的职权范围。因此，我们将允许调查继续进行，我们有信心特勤局将查明真相，”她说，强调总统和他的家人上周末不在白宫。
“从周五晚上到周日，通常会在工作人员、国会议员和其他有特权的人的带领下参观西翼，”前美国特勤局特工唐·米哈莱克说。"据称，这一发现发生在一个任何参观白宫的人都可以进入的地方。"
现在是美国广播公司新闻撰稿人的米哈莱克说，特勤局的筛选发生在“进入西行政广场之前，这是西翼之旅的会面地点。”
他说:“这项检查包括磁力计和行李x光检查。”。"导游最终要对他们的旅游团负责。"
米哈莱克说，这一事件进一步加强了白宫让特勤局在审查所有访问白宫的个人时发挥“加强作用”的必要性，“以确保白宫的安全”。
一名委员会官员告诉ABC新闻，共和党领导的众议院监督委员会计划要求特勤局就在白宫发现的可卡因进行简报。
“美国特勤局允许这种物质在白宫通过国会资助的广泛筛选过程。监督委员会将要求特勤局做一个简报，”委员会助手说。
Secret Service test confirms cocaine found at White House, spokesman says
Lab testing has confirmed it wascocaine found in the White House West WingSunday evening, a U.S. Secret Service spokesman said Wednesday.
The investigation into how it got there is ongoing.
The white powder was found during a routine search, a source said, and a preliminary field test had showed the substance tested positive for cocaine.
The cocaine was found on the ground floor of the White House, near the West Executive entrance where visitors are instructed to typically drop off their cell phones, according to a source familiar with the matter.
Some visitors, but not members of the general public, are able to tour parts of the West Wing, and tours typically take place on the weekends.
White House press secretary Karine Jean-Pierre confirmed Wednesday there had been tours this past Friday, Saturday and Sunday.
President Joe Biden and family members were at Camp David at the time.
Jean-Pierre told reporters Wednesday "the president thinks is incredibly important to get to the bottom" of how the cocaine came to be at the White House, but she deferred almost all questions to the Secret Service as it continues its investigation.
"Where this was discovered is a heavily traveled area where many White House -- West Wing, I should be even more specific, West Wing visitors come through this particular area. I just don't have anything more to share," she said.
"It is under investigation by the Secret Service. This is in their purview. And so we're gonna, going to allow, certainly the investigation to continue and we have confidence that the Secret Service will get to the bottom of this," she said, emphasizing that the president and his family were not at the White House this past weekend.
"From Friday night to Sunday, West Wing tours usually occur, led by staff, members of Congress and others who have that privilege," according to former U.S. Secret Service agent Don Mihalek. "The discovery allegedly took place in an area widely accessible to anyone visiting the White House."
Mihalek, now an ABC News contributor, said Secret Service screening occurs "prior to entry on West Executive Place, which is where West Wing tours meet up."
"That screening includes a magnetometer and X-ray of bags," he said. "The person leading the tour is ultimately responsible for their tour group."
Mihalek said the incident further reinforces the need for the White House to have the Secret Service take an "enhanced role" in vetting all individuals visiting the White House "to keep the White House safe."
The Republican-led House Oversight committee plans to request a briefing from Secret Service on the cocaine found at the White House, a committee official told ABC News.
"The U.S. Secret Service allowed the substance in the White House through their extensive screening process that Congress funds. The Oversight Committee will request a briefing from Secret Service," the committee aide said.
