Jones says she was raped while working for KBR at Camp Hope in Baghdad in 2005. She's asking for unspecified damages from the Houston-based companies, which split in 2007.
She sued KBR, Houston-based former parent Halliburton Co. and a former KBR worker she alleges raped her. All deny Jones' allegations.
The Associated Press usually doesn't identify people alleging sexual assault, but Jones' face and name have been in media reports and on her own website.
