An envelope containing a suspicious substance arrived at Rep. Suhas Subramanyam's district office on Wirt Street in Leesburg early Monday morning, triggering an evacuation and a hazmat response. No injuries were reported, and the building was later cleared and returned to its occupants.

The Loudoun County Fire and Rescue hazardous materials team was dispatched to the 200 block of Wirt Street just after 9 a.m., according to Rappahannock News. Subramanyam said in a statement that “my office in Leesburg received an envelope containing a suspicious substance. The office was promptly evacuated,” as reported by Loudoun Now.

Leesburg Police, Loudoun County Fire and Rescue's hazmat team and U.S. Capitol Police all responded to the scene, with Subramanyam thanking “the Leesburg Police, Loudoun County Fire and Rescue and their Hazmat team, and the Capitol Police,” according to FOX 5 DC. The scene was ultimately deemed safe and the building handed back to its occupants, the same outlet reported, and preliminary testing found the powder to be non-hazardous.

Congressman Calls Out Political Intimidation

Subramanyam, a Democrat whose office received the envelope on Wirt Street early Monday, framed the incident in stark terms. According to NBC Washington, he said “these acts of political intimidation have no place in our country.” The outlet also reported that the Leesburg mailing came after at least 25 state election offices and at least 10 offices of congressional Democrats reportedly received suspicious letters, though that tally differs from other counts of the broader wave of mailings.

It remains unclear whether the envelope sent to Subramanyam's office is connected to that larger pattern of mailings under federal investigation, according to WTOP. Coverage from KABB similarly noted that authorities had not released additional details about the substance or the investigation as of Monday.

Part of a Wider Wave of Mailings Nationwide

The Leesburg incident landed amid a sprawling federal probe. Federal law enforcement has been investigating dozens of letters containing suspicious substances mailed to congressional offices and state election officials across the country, the FBI, U.S. Capitol Police and U.S. Postal Inspection Service were looking into the mailings, per NBC News. That outlet reported that election offices in at least 15 states said they were mailed suspicious packages, while CNN separately reported that at least 36 lawmakers across the country reported their offices receiving suspicious letters during the same week, figures that vary depending on the source and reporting window.

Preliminary testing of the white powder substance in those mailings showed that the contents are not hazardous, though additional testing was planned, the NBC News report noted. The wave of mailings has unfolded less than three weeks before Election Day, scheduled for Nov. 3, according to the same report.

Similar Scares Hit Offices Across the Country

Leesburg is far from alone. Officials intercepted a suspicious letter before it reached Sen. Amy Klobuchar's Minnesota office, while a regional security team in South Dakota contacted local authorities, who investigated and evacuated Sen. Mike Rounds's Sioux Falls office, according to The Hill. A staff member at Rep. Jimmy Panetta's Santa Cruz office opened an envelope containing suspicious white powder and called 911 after clearing the building, the outlet reported, and Reps. Laura Friedman, Gil Cisneros and Linda Sánchez also reported suspicious packages at their district offices, with staff said to be safe.

In Florida, Rep. Maxwell Frost announced the evacuation of his Magnolia Street office in Orlando due to a suspicious package, as reported by the Orlando Sentinel. The same report noted that Rep. Darren Soto said law enforcement had intercepted an envelope containing a suspicious substance sent to his Kissimmee office before it reached staff.

Arizona State Capitol offices were evacuated after staff opened an envelope filled with white powder, prompting a quarantine and hazmat response, and Texas Sen. Ted Cruz said his Houston office received a suspicious letter containing white powder, according to CNN. Sens. Pete Ricketts and Mike Rounds also confirmed their offices received letters containing a white powder substance, and Louisiana Secretary of State Nancy Landry said law enforcement found no evidence of harmful substances after testing powder from a package sent to her office, per The Hill's separate report on the targeted mailings.
