Katie Arrington, who upset Rep. Mark Sanford for the Republican 1st Congressional District nomination two weeks ago in South Carolina, was involved a fatal car accident late Friday, with Arrington sustaining serious injuries requiring surgery, the Post and Courier reports.

Arrington, who received the endorsement of President Donald Trump, sustained a fracture in her back, several broken ribs and suffered a collapse of the main artery in her leg. The report states that Arrington already underwent surgery to remove her small intestine.

According to the report, Arrington was lucid and talking.

The report states that the GOP candidate was a passenger in the car heading south toward Hilton Head Island when the vehicle she was in was struck by another car driving northbound but in the wrong lane. The driver in the other car was killed.

Arrington was slated to undergo further surgery on Saturday morning and  it was initially estimated she would be in the hospital for two weeks.
