AUGUSTA, Maine — The Maine Republican Party headquarters in Augusta was evacuated Thursday afternoon after staff received an envelope containing an unidentified white powder, prompting a hazmat response and an on-site quarantine for people inside the building, party officials said.
According to a new statement released by the Maine GOP, the envelope arrived in the mail and contained “an unidentifiable white powder.” The building was evacuated, and individuals who had been inside were required to remain on site in quarantine “until further evidence was uncovered regarding the substance.”
Augusta emergency services responded to coordinate the investigation, and the National Guard’s hazardous materials team arrived within an hour to begin cleanup inside the building, the party said.
By 4:45 p.m., the office was informed the building had been cleaned and that the substance was “not believed to be harmful,” though officials said more complete testing would continue overnight.
Maine Republican Party Chairman Jim Deyermond condemned the incident and warned that increasingly heated politics are creating real safety concerns.
“These are crazy times, and we must continue to remain diligent for our own and others’ safety,” Deyermond said. “This will not impact the functions or dedication of the Maine Republican Party to elect Republicans and work for a better tomorrow. It’s frustrating to be interrupted and have potential extreme ill-intent impacting our operations and staff. The rhetoric and violence need to be toned down before more people get hurt. We are thankful no one was harmed today.”
The Republican National Committee also weighed in, casting the incident as political violence regardless of what the substance turns out to be.
“Regardless of what substance is determined to be in that envelope, whether the goal was intimidation or physical harm, this is a disgusting act of political violence against Maine’s Republican party,” said RNC spokesperson Kristen Cianci, who also blamed Democrats for “raising the temperature” and “demonizing our party to gain political points.”
The Maine GOP executive director was more blunt, calling the incident an “attack” and framing it as part of a broader pattern of hostility toward Republican officials and activists.

“This was an attack. It’s unnecessary, and it escalates an already combative, high-strung political environment in Maine,” the executive director said. “We are tired of being verbally and now physically attacked. We are more driven than ever to win big in 2026 and take back our state.”
“It is important not to be desensitized to the seriousness of this situation, and we are glad that no one has been hurt,” the executive director added.
Party officials said additional testing on the substance was expected to be completed overnight.
Probably a High School or College Student…They don’t know how to fill out envelopes as it
is not taught in school. Sad. Glad no one was hurt!
