What is going on? The mystery behind suspicious packages sent to Florida congressional offices

October 18, 2026 — A series of suspicious mail deliveries targeting congressional and election offices across the United States has reached Central Florida, raising security concerns just weeks before the November 3 midterm elections.

Two Democratic members of Congress, Maxwell Frost of Orlando and Darren Soto of Kissimmee, reported receiving suspicious mail on Friday, October 16, prompting emergency responses and investigations involving local and federal authorities.

The incidents were not isolated. Similar deliveries have been reported at congressional and election offices in multiple states, raising questions about who is responsible and whether the mailings are connected.

The situation began in downtown Orlando when Congressman Maxwell Frost’s office received a suspicious package resembling deliveries reported elsewhere in the country.

Frost announced that his office had been evacuated as a precaution and that the U.S. Capitol Police and Orlando Police Department had been notified.

Emergency responders arrived at the location, and a large section of Magnolia Avenue was closed while authorities investigated.

Hazardous materials personnel were also seen responding to the scene, highlighting the precautions taken when an unidentified package could potentially contain dangerous substances.

Frost confirmed that he and his employees were safe and cooperating with law enforcement.

Approximately 45 minutes later, another alarming development emerged in nearby Kissimmee.

Congressman Darren Soto’s office reported receiving an envelope containing an unidentified substance.

However, the envelope was intercepted by local law enforcement before staff members were exposed to its contents.

Soto’s office explained that the warning from Frost’s team had helped employees recognize the potential danger and monitor incoming mail more carefully.

No injuries were reported at either congressional office.

The two incidents have attracted additional attention because they occurred amid a broader federal investigation into suspicious letters delivered or addressed to political and election-related offices nationwide.

Federal agencies, including the FBI, U.S. Postal Inspection Service, and U.S. Capitol Police, have been investigating reports of envelopes containing unknown substances.

The mailings have affected offices associated with several prominent lawmakers, including Democratic senators in Delaware, California, and New York.

Election offices in numerous states have also reported suspicious deliveries, prompting heightened security precautions.

In some cases, the envelopes reportedly contained powder-like materials, leading authorities to isolate the items and conduct safety testing.

Not every suspicious substance has proved dangerous. Testing determined that at least one powdery substance sent to an election office in Wisconsin was not hazardous.

Florida’s Division of Elections was also among the institutions affected by the broader series of suspicious mailings.

State officials confirmed that federal authorities had intercepted a suspicious package before it reached the Florida Department of State.

The incidents come during a politically sensitive period as election officials prepare for the November 3 midterm elections.

Security specialists say that suspicious deliveries can disrupt government operations even when the materials ultimately prove harmless.

Such incidents can force evacuations, interrupt public services, and require significant emergency resources while investigators determine whether a genuine threat exists.

For investigators, identifying the sender may involve examining postal records, surveillance footage, packaging materials, and other evidence associated with the deliveries.

Authorities have not publicly established whether the two Central Florida incidents were coordinated or whether they are directly connected to every other suspicious mailing reported nationwide.

The exact contents of the packages sent to Frost and Soto’s offices have also not been publicly confirmed.

There has been no verified announcement establishing that either Florida package contained an explosive device or a toxic substance.

The identity of the sender and the motive behind the deliveries remain unknown.

For now, the incidents leave several questions unanswered: Who sent the suspicious mail? Why were congressional and election offices targeted? And are the cases part of a coordinated nationwide campaign?

As federal and local investigations continue, the safety of public officials, their employees, and election workers rem
