FORT SMITH, Ark. (AP) — An Arkansas woman appeared Wednesday in court on charges she threatened to blow up Gov. Sarah Huckabee Sanders and her office, prosecutors said.

Susan Scott, 66, of Fort Smith, was charged with threatening to cause a catastrophe and battery of an officer in the second-degree, both felonies, Sebastian County Prosecuting Attorney Daniel Shue said in a news release.

Police said on June 14, Scott was still making threats against Sanders when they went to arrest her at her home. Scott resisted arrest and “head-butted” an officer, according to an affidavit.

Scott appeared before Circuit Judge R. Gunner DeLay without an attorney and the public defender’s office was appointed to represent her, Shue said. A plea of not guilty was entered on her behalf, he said. A telephone message left with the public defender’s office was not immediately returned.

DeLay set bond for Scott at $500,000. A trial date has not been set.
