Far-left activists associated with Antifa and other radical hate groups attacked the Republican Party headquarters in New York City late Thursday evening; vandalizing the historic building and warning the incident was “merely the beginning.”

Our attack is merely a beginning. We are not passive, we are not civil, and we will not apologize

The New York GOP released shocking images immediately following the assault; writing “The New York Republican New York City headquarters at the Metropolitan Republican Club was physically vandalized last evening with broken windows, spray-paint and more.”

The attackers left an ominous note at the scene, saying “The U.S. government has established concentration camps around the country for Latino people, shamelessly murdering black people, and continues its war machine that has slaughtered Muslim people with impunity for decades.”

“Our attack is merely a beginning. We are not passive, we are not civil, and we will not apologize. Those of good conscience and clear mind know this state of oppression cannot remain. The US fascist political system is one of the most savage institutions in history and we will combat it relentlessly until all are free of American barbarism,” adds the note.
