Former Vice President Al Gore is suing Al Jazeera America, saying the news network is withholding tens of millions of dollars that it owes for buying Current TV from him and other shareholders for $500 million last year.
David Boies, Gore's attorney, said in a statement that Al Jazeera America "wants to give itself a discount on the purchase price that was agreed to nearly two years ago."
Al Jazeera America did not immediately respond to a request for comment.
Boies says the suit was filed in Delaware Court of Chancery on Friday.
The Qatar-owned news channel began sending out its signal to more than 45 million homes last August after hiring a slew of U.S. TV news veterans like Soledad O'Brien and John Seigenthaler.
