The FBI is investigating after suspicious letters were sent to the offices of three Democratic members of Congress from Arizona, in what appears to be part of a wider wave of threatening mail aimed at elected officials and election offices just weeks before the Nov. 3 midterm elections. Representatives Greg Stanton, Yassamin Ansari and Adelita Grijalva disclosed the letters on Oct. 19, saying federal authorities notified them over the weekend and vowing, "We will not be intimidated."

Federal officials say the offices of U.S. Reps. Adelita Grijalva, Greg Stanton and Yassamin Ansari — all Democrats representing Arizona districts — received what law enforcement described as "suspicious letters," some containing unknown substances. According to reports, the FBI's Phoenix field office and the Arizona Department of Homeland Security informed the lawmakers over the weekend of Oct. 17-18 that the mailings had been directed at their offices.
The three lawmakers issued a joint statement on Oct. 19 detailing what they had learned. According to the statement, the letter addressed to Rep. Stanton's district office in Mesa was intercepted before it could be delivered, while the letters sent to Reps. Ansari and Grijalva had been mailed to their former office addresses. The FBI and the U.S. Postal Inspection Service are now investigating, the lawmakers said.
The Lawmakers' Response
In their joint statement, the three Arizona Democrats said they had been told that similar letters — many containing unknown substances — have been mailed to elected officials across the country. "We're grateful to law enforcement for acting quickly and keeping our staff and communities safe," the statement read. "We will not be intimidated and we'll keep doing the work that Arizonans elected us to do."
Ansari echoed that message on social media on Oct. 19, writing: "Threats and intimidation will never stop us from being public servants, and we'll continue doing the work that Arizonans elected us to do."
The three represent neighboring Arizona House districts: Stanton represents Arizona's 4th District, Ansari the 3rd District, and Grijalva the 7th District. All three are Democrats serving in the U.S. House of Representatives.
According to a KTAR News report cited by Headlines Plus, the letters received by the three lawmakers contained white powder, and authorities are working to determine what the substance is and who is responsible for sending the packages. No injuries have been reported.
A Wider Wave of Threat Mail
On Oct. 15, the Arizona Executive Tower at the state Capitol complex in Phoenix was evacuated after staffers in the Secretary of State's office opened an envelope containing white powder, according to azcentral. Two days earlier, the Louisiana Secretary of State's office in Baton Rouge reported a similar incident, with staffers finding a package containing white powder. Election officials in Ohio and Oklahoma also reported receiving suspicious packages earlier in October. Local media in those states reported no injuries in any of the incidents.
Fox 10 Phoenix reported last week that federal law enforcement officials were already investigating suspicious letters sent to election offices nationwide as the Nov. 3 general election nears. According to the FBI and the U.S. Postal Inspection Service, the series of letters was also sent to offices on Capitol Hill, with a return address for the Democratic Socialists of America headquarters in New York City. Officials described the letters as "potentially hazardous," though the details of the exact chemical contents were not released, Fox 10 reported.
The wave has reached lawmakers beyond Arizona. Rep. Joe Neguse of Colorado was reported to be one of roughly 30 lawmakers sent suspicious mail containing white powder, and Utah Lt. Gov. Deidre Henderson — a Republican and Utah's chief election officer — wrote that her local postal inspector intercepted a letter and handed it off to the FBI before it could be delivered to her office. "Nothing is going to disrupt the midterm election. We won't let it happen," Henderson posted.
"We Will Not Be Intimidated"
The incidents have drawn condemnation as attacks on election administration, with lawmakers from both parties warning that threats against public servants must be answered regardless of the target's party affiliation.
The timing — just weeks before voters head to the polls on Nov. 3 — has amplified concern. Election administration has become a lightning-rod issue in recent campaign cycles, and the string of incidents from Arizona to Louisiana to Ohio has put federal agencies on alert.
The FBI has not released details about what the letters contained, who may have sent them, or whether any arrests are expected. Investigations by the FBI's Phoenix field office and the U.S. Postal Inspection Service remain ongoing, according to the lawmakers' statement.

What This Means
The suspicious letters land at a moment of already-heightened tension around American elections. With the midterms only days away, any threat against the people who run elections — or the lawmakers who oversee them — carries weight far beyond the envelopes themselves. Even when no one is physically harmed, as has been the case in every reported incident so far, each evacuation and each investigation consumes law enforcement resources and feeds a climate of fear around civic life.
The bipartisan nature of the targets is notable. While the three Arizona lawmakers are Democrats, the mailings have also reached a Republican lieutenant governor and election offices in states controlled by both parties. The through-line is not ideology but office: the people who administer and represent American democracy are the ones being targeted.
What Happens Next
The FBI and the U.S. Postal Inspection Service investigations will determine what the substances were, whether they were dangerous, and who sent them. Mailing threats or harmful substances to elected officials is a serious federal crime, and federal prosecutors have historically pursued such cases aggressively.
For the Arizona lawmakers, the immediate message is defiance. As Stanton, Ansari and Grijalva wrote in their joint statement: "We will not be intimidated and we'll keep doing the work that Arizonans elected us to do." With the Nov. 3 election approaching, election officials across the country will be watching the investigations — and their own mail — closely.
