Former U.S. Vice President Al Gore has filed a lawsuit in the Delaware Court of Chancery alleging Al-Jazeera America Holdings Inc. is withholding $65 million owed to Current Media’s shareholders after the Qatar-based news agency last year paid roughly $500 million for the cable network.

The initial complaint was filed under seal, but a statement of good cause filed with the lawsuit detailed a portion of the dispute. Gore, who was Current’s executive chairman of the board, and Joel Hyatt, the network’s vice chairman, alleged breach of contract and fraud claims in the litigation, filed late Aug. 15.
