FBI probes mystery mailings as election offices evacuate — and ‘DSA’ appears on an envelope

THE DAILY BS: HOW MUCH CAN YOU HANDLE?

SPARE ME THE BS (I’ve got things to do).

The FBI, Capitol Police and postal inspectors are investigating letters containing unidentified substances sent to congressional and election offices nationwide.
One envelope bore “DSA” and a Manhattan return address formerly used by the Democratic Socialists of America, which says it left the location in 2013.
Election offices in Louisiana and Oklahoma have been evacuated, while Ohio intercepted another suspicious package just weeks before the midterms.

LAY IT ON ME (I’ve got time).

Somebody is mailing suspicious substances to government offices across America, federal investigators are scrambling to intercept the letters, and one envelope carries a return address with a rather curious political connection.

It says “DSA.”

That’s also the abbreviation for the Democratic Socialists of America, the left-wing political organization whose former Manhattan address appears on the envelope.

But before anyone starts pointing fingers, there’s a rather important complication: the organization says it hasn’t operated from that address in more than a decade.

Welcome to the latest mystery confronting federal law enforcement just weeks before the November midterm elections.

The FBI, U.S. Capitol Police and U.S. Postal Inspection Service are investigating multiple letters containing suspicious substances mailed to congressional offices and other government addresses nationwide.

Ohio Secretary of State says his office was an intended recipient:

According to an emergency notice distributed to Senate offices Thursday, authorities are attempting to intercept additional letters before they reach their intended recipients.

But the warning contained an unsettling qualification.

“Law enforcement officials are working to intercept any additional letters before they are delivered, however, it is possible that some letters may reach their destinations,” the notice said.

In other words, investigators don’t yet know whether they’ve found them all.

The warning included a photograph of one envelope bearing the letters “DSA” and listing 75 Maiden Lane in Manhattan as its return address.

That building previously housed the Democratic Socialists of America, whose membership materials once listed the same address.

NEW: The FBI, US Postal Inspection Service and Capitol Police are investigating letters “containing suspicious substances” that were mailed to congressional offices, according to an email sent to Hill staff Thursday

The organization quickly distanced itself from the mailing.

“DSA has not occupied this office address since 2013,” a representative said. “We are also no longer headquartered at 75 Maiden Lane.”

There is currently no publicly established evidence connecting the organization to the suspicious mailings. Return addresses can be falsified, and investigators have not identified the sender.

But the discovery has added another question to an already troubling investigation. Who sent the letters, what exactly is inside them, and why was an address formerly associated with a political organization placed on at least one envelope?

Meanwhile, the investigation has expanded well beyond Capitol Hill.

The Associated Press reports that suspicious mailings have also targeted secretary of state offices and election facilities around the country.

Packages containing unidentified powder prompted evacuations at election offices in Louisiana and Oklahoma.

In Ohio, Secretary of State Frank LaRose announced that postal investigators intercepted a package containing a white powdery substance before it reached his office.

LaRose said authorities were investigating similar mailings directed at election officials in other states and warned county election boards to remain vigilant.

The FBI confirmed the broader investigation in a statement Thursday.

“The FBI and U.S. Postal Inspection Service are investigating a series of suspicious mailings sent to various addresses nationwide, including Secretary of State offices and their related election offices,” the bureau said.

“Some of the letters contained an unknown substance, and we are working closely with our law enforcement partners to respond to each incident.”

Investigators are also attempting to identify whoever is responsible.

So far, authorities have not publicly established what the substances are, whether they are toxic or whether the same person or group sent every mailing.

The timing is particularly unsettling.

With Election Day less than three weeks away, state and local election officials are already preparing for one of the busiest periods on their calendars. Now some are dealing with evacuations and suspicious packages.

The National Association of Secretaries of State and the National Association of State Election Directors issued a joint statement condemning threats against election workers.

“Those who administer our elections should never fear for their safety while carrying out their essential duties,” the organizations said.

There’s also an eerie historical coincidence. The latest warnings arrived on October 15, exactly 25 years after an anthrax-contaminated letter was opened in the Washington office of then-Senate Majority Leader Tom Daschle.

The 2001 anthrax attacks ultimately killed five people and sickened at least 17 others, triggering a massive federal investigation and fundamentally changing how congressional mail is screened.

Today’s suspicious letters have not been identified as containing anthrax. But the history explains why Capitol Hill takes even an apparently ordinary envelope containing unidentified powder extremely seriously.

Congressional mail now passes through specialized screening facilities, where potentially dangerous materials can be detected before reaching lawmakers and their staffs.

Even so, Thursday’s warning made clear that officials cannot guarantee every suspicious mailing has been intercepted.

And that brings us back to the envelope bearing the old Democratic Socialists address. Was it a deliberate attempt to implicate the organization? A misleading return address intended to confuse investigators? Or something else entirely?

Federal authorities haven’t said.
