Writing on Twitter, Mr Trump suggested last night's suspected terror attack was an attempt by Democrats to derail his Presidental bid. The office, in the town of Hillsborough, was set on fire when thugs launched a bottle of flammable liquid through the front window. The words "Nazi Republicans get out of town or else" were spray-painted on a nearby building, along with a swastika.

Mr Trump tweeted: "Animals representing Hillary Clinton and Dems in North Carolina just firebombed our office in Orange County because we are winning." He later wrote: "All safe in Orange County, North Carolina. With you all the way, will never forget. Now we have to win. Proud of you all!" And Mrs Clinton told supporters: "The attack on the Orange County HQ @NCGOP office is horrific and unacceptable. Very grateful that everyone is safe."

Dallas Woodhouse, chief executive of the North Carolina Republican Party, vowed to ramp up security at events and offices. He said: "Whether you are Republican, Democrat or independent, all Americans should be outraged by this hate-filled and violent attack against our democracy." Mr Woodhouse added: "Everyone in this country should be free to express their political viewpoints without fear for their own safety.

SG Hillsborough mayor Tom Stevens condemned the 'disturbing' attack

"We will be requesting additional security between now and Election Day to ensure the safety of our activists, volunteers, and supporters." A police spokesman said the flammable liquid "ignited inside the building, burned some furniture and damaged the building's interior" before going out. Hillsborough mayor Tom Stevens said the attack was "highly disturbing" and "goes far beyond vandalising property".
