华盛顿讯 — 联邦调查人员周三表示，他们正在调查寄给州选举官员和国会议员办公室的“可疑”信件，其中部分信件含有不明物质。
美国邮政 Inspection Service（USPIS）副首席检查员布伦丹·多纳休表示，联邦调查局和美国邮政监察局正在调查这些“可疑邮件”。多纳休对记者称，部分信件内含有不明物质，收件地址遍布美国全国，包括“国务卿办公室及相关选举办公室”。
“我们致力于保护国家选举官员免受威胁性和危险性邮件的伤害。任何针对选举官员的威胁或攻击都是不可接受的，”多纳休说道。“我们的合作伙伴，包括联邦调查局，以及我们邮政监察局，将动用所有资源推进这些调查。”
参议院 Sergeant-at-Arms（参议院持剑官，即参议院警卫长）也向国会工作人员发布了通知，通报此次调查。哥伦比亚广播公司新闻获得的这份通知显示，国会办公室也是可疑信件的收件方之一。
康涅狄格州民主党参议员克里斯·墨菲的一名发言人表示，他的办公室是目标之一。
“墨菲参议员的办公室收到了一封带有可疑物质的信件。联邦调查局、参议院警卫长和国会警方及时向我们办公室通报了这一情况，我们目前正与他们及联邦执法部门密切合作，”墨菲的发言人乔希·索布说道。“由于这些应对措施和各项安全规程，参议员和工作人员并未面临即时危险。”
据加利福尼亚州民主党参议员亚历克斯·帕迪利亚的一名发言人透露，帕迪利亚的办公室也收到了一封可疑信件。
“我们收到联邦调查局的通知，称我们的一间办公室收到了一封内含可疑物质的信件，但该信件已被美国邮政局截获，”该发言人表示。
众议院警卫长向众议院各办公室发布通知称，目前已知没有议员成为目标。
多纳休表示，联邦官员正在努力确认责任人，并已截获部分信件。多纳休以调查仍在进行为由，拒绝透露具体案件数量或讨论可能存在的关联。他补充道，调查人员将动用全部资源处理这些案件。
此次事件距离中期选举不到三周。联邦调查人员也曾在2024年大选前调查过一系列可疑信件。
除国会办公室外，至少两个州的高级选举官员报告称，其办公室近期收到了装有白色粉末的包裹。
路易斯安那州国务卿南希·兰德里周二表示，该办公室选举部门的一名员工拆开了一个包裹，发现里面是白色粉末。
“执法人员赶到现场并进行了检测，未发现有害物质，”她在脸书上写道，并补充称无人受伤。
俄克拉荷马州选举委员会表示，其办公室于周二上午收到了一个装有“可疑”白色粉末的信封，随后办公室被疏散。
选举委员会秘书保罗·齐里亚克斯表示，此次事件未造成人员受伤，执法部门正在调查中。

Washington — Federal investigators said Wednesday that they are looking into “suspicious” letters mailed to state election officials and congressional offices, some of which contained unknown substances.
The FBI and U.S. Postal Inspection Service are investigating the “suspicious mailings,” according to Brendan Donahue, the deputy chief inspector at the USPIS. Donahue told reporters that some letters have contained an unknown substance and that they were sent to “various addresses nationwide,” including “secretary of state offices and the related election offices.”
“We are committed to protecting our nation’s election officials from threatening and dangerous mail. Any threat or attack on an election official is unacceptable,” Donahue said. “Our partners, including the FBI and we at the Postal Inspection Service, will bring all of our resources to bear on these investigations.”
The Senate sergeant at arms also issued a notice to congressional staff informing them of the investigation. The message, which was obtained by CBS News, said congressional offices were among those who received the suspicious letters.
A spokesman for Democratic Sen. Chris Murphy of Connecticut said his office was one of those targeted.
“Sen. Murphy’s office was sent a letter with a suspicious substance. Our office was promptly informed of the letter by FBI, SAA, and Capitol Police, and we continue to work closely with them and federal law enforcement,” said Josh Sorbe, a spokesman for Murphy. “Due to those efforts and various safety protocols, the Senator and staff were not in immediate danger.”
A letter was also sent to Sen. Alex Padilla’s office, according to a spokesperson for the California Democrat.
“We received the notification from the FBI that one of our offices was mailed a letter containing a suspicious substance, but it was intercepted by USPS,” the spokesperson said.
The House sergeant at arms sent a notice to the lower chamber’s offices stating that no House members were known to have been targeted.
Federal officials are working to identify the responsible parties and have intercepted some of the letters, Donahue said. Donahue declined to provide an exact number of incidents or discuss possible connections, citing the ongoing investigation. He added that investigators would bring their full resources to bear on the cases.
The development comes less than three weeks before the midterm elections. Federal investigators also probed a series of suspicious letters ahead of the 2024 elections.
In addition to the congressional offices, top election officials in at least two states reported that their offices received packages containing a white powder in recent days.
Louisiana Secretary of State Nancy Landry said Tuesday that an employee in her office’s Elections Division opened a package and found a white powder.
“Law enforcement responded to today’s incident and conducted tests that found no evidence of harmful substances,” she wrote on Facebook, adding that no one was injured.
The Oklahoma State Election Board said it received an envelope containing “suspicious” white powder Tuesday morning, and its office was evacuated.
Paul Ziriax, secretary of the election board, said no one was hurt as a result of the incident, and law enforcement is investigating.
