Senator Elizabeth Warren and other members of Congress are fighting the proposed purchase of power company AES by a consortium led by BlackRock. These legislators have called on energy regulators to reject the $33.4 billion deal and prevent the transfer of the utility company.

The BlackRock-led consortium is currently seeking the government approvals necessary to finalize the takeover. The intervention by Warren and her colleagues is a direct effort to pressure regulators to deny the transaction during the review process.
