President Trump appointed a Republican to head the Federal Energy Regulatory Commission on Thursday after restoring the quorum at the independent grid watchdog.

Neil Chatterjee, a top GOP energy adviser, was made the new FERC chairman soon after another Republican, Robert Powelson, was sworn in as FERC commissioner. He will replace Democratic acting Chairwoman Cheryl LaFleur, who Trump put in that position right before former President Barack Obama’s chairman appointee resigned, which left the panel without at least three commissioners required to run the regulatory body.
