Last Sunday, over 100 members of Antifa gathered for a memorial for 23-year-old activist Sean Kealiher, who was killed in a hit and run accident near Cider Riot, a left-wing and Antifa hangout in Northeast Portland.

During the vigil, an Antifa member was filmed as he climbed onto the ledge at the headquarters of the Democratic Party of Oregon and spray painted an anarchist symbol.

The building is covered with massive amounts of graffiti sprayed by Antifa members who used spray paint and chalk to write expletives and political messages such as “ACAB,” “Abolish ICE,” and “Resist.”

Molly Woon, the deputy director of the Democratic Party of Oregon, told Fox 12 News they will focus on ways to maintain a supportive environment for their employees and for those who are mourning Kealiher’s death.

The statement reads: “Although the graffiti to our building is significant, any damage is insignificant compared to the community’s tremendous grief over this senseless death.”

The vandal got cheers and applause from other Antifa members as he defaced the building with the anarchy symbol.

In the video that was posted to Twitter, the group can be heard chanting “ACAB - All cops are bastards” during the display of flares and fireworks they used for Kealiher’s vigil.

The police are investigating the death of Kealiher as a homicide. No arrests have been made yet.
