 On May 3, Sinclair officially announced that via its subsidiary Diamond Sports Group, it had agreed to purchase the networks for $10.6 billion, pending regulatory approval.At the same time, it was also revealed that Entertainment Studios would hold an equity stake in the company and serve as a "content partner".Three senators (Cory Booker, Bernie Sanders, and Elizabeth Warren) called for the sale to be reviewed by the Department of Justice, citing concerns over Sinclair's history of partisan right-wing political views in the news programming of its local television stations, and that it could use the networks as leverage for carriage agreements for its broadcast television stations.
