The online smear campaign began early in 2012 and included fake Twitter feeds, Facebook pages and fan club sites. Chidiac, according to the lawsuit, said he could mount such attacks and the paper "would never know it was him."
The smears ended in late April after Pentagon officials were alerted to it. Chidiac acknowledged his role in creating the websites in May but said he had done so as a private citizen. He promised to sell his stake in the company but has not done so, said Gar Smith, a Leonie spokesman.
Jason Fandrich, an attorney for Chidiac, called the accusations in the lawsuit frivolous and without merit.
The Pentagon declined to comment on the lawsuit.
