The U.S. District Court in Virginia has given Marshal Khalifa Haftar two weeks "to answer questions in a lawsuit accusing him of war crimes."
Earlier this year, Judge Leonie Brinkema, "rejected Haftar's argument that he had immunity, and allowed the case to move forward," according to the Associated Press.
Haftar still holds U.S. citizenship and still owns extensive property in Virginia.
Lawyers for the plaintiffs are taking depositions in the case and want to depose Haftar as well.
He has sought to block the depositions. In court papers his lawyers argue that requiring him to answer questions would force him to violate Libyan law by disclosing state secrets, subjecting him to a possible death sentence.
On Thursday, U.S. District Judge Leonie Brinkema again rejected Haftar's argument, and set an Oct. 28 deadline for the deposition to take place.
