Kevin McIntyre, who briefly served as chairman of the Federal Energy Regulatory Commission (FERC), died Jan. 2 at age 58. He had been diagnosed with brain cancer in 2017 and had surgery to remove a tumor.

President Trump nominated McIntyre, a Republican, in August 2017 to serve as FERC chairman. He was confirmed by the Senate in November of that year—the delay was attributed to his health— and sworn in on Dec. 7, 2017, just prior to his 57th birthday. The nature of his health problems was not made public until March 2018.

At that time he said his prognosis was good, owing to “excellent health” and ongoing treatment. He said: “For reasons of personal and family privacy, I do not intend to provide further details or updates on this subject.”

McIntyre was the co-leader of the global energy practice at the law firm Jones Day prior to his nomination to FERC. He led a large FERC practice at Jones Day, representing clients in several energy sectors.

McIntyre held degrees from San Diego State University and Georgetown University Law School. His wife, Jennifer, and three children survive him.
