PORTLAND, Ore. (AP) — An Iraq war contractor that lost an $85 million verdict to a group of sickened Oregon soldiers has filed a lawsuit seeking to force the federal government to pay the soldiers’ damages.

In early November, 12 Oregon National Guard soldiers won the verdict against Kellogg Brown and Root, an engineering and construction firm that helped lead the reconstruction work in post-war Iraq. The soldiers were exposed to a toxin while guarding an Iraqi water plant.
