A group of Democrats came together Sunday to raise money to rebuild a Republican headquarters that was firebombed in North Carolina on Saturday night.

The GOP headquarters in Orange County, N.C., suffered major damage when an explosive device was thrown through a window on Saturday night, according to officials. The words “Nazi Republicans leave town or else” were spray-painted on a nearby building.

Dallas Woodhouse, executive director of the North Carolina Republican Party, denounced the attack, calling it “political terrorism.” He said all Americans “should be outraged by this hate-filled and violent attack against our democracy.”

On Sunday, David Weinberger began a GoFundMe page to raise $10,000 to rebuild the Hillsborough, N.C., headquarters.

“As Democrats, we are starting this campaign to enable the Orange County, N.C., Republican office to re-open as soon as possible,” the page said in the story section.

The group said that while it’s still unclear who attacked the office, or why, one thing is clear: “This is not how Americans resolve their differences.”

“We talk, we argue, sometimes we march, and most of all we vote. We do not resort to violence by individuals or by mobs,” the group said. “So, let's all pitch in, no matter what your party affiliation, and get that office open again quickly.”

Within forty minutes of posting, the group surpassed the goal and raised $13,117. Many of those who donated made comments about supporting people regardless of party affiliation.

"Not a Republican, but we all stand together against such anti-democratic violence," one person wrote, while another said, "This Democrat from Indiana hopes you're able to get your back to your office as soon as possible."

The group is no longer accepting donations but asked that those who want to contribute donate to a North Carolina school through Donors Choose.
