Jan. 27 — A U.S. energy regulator filed his letter of resignation on Thursday. And with that letter, he may have just brought federal decisions on multibillion-dollar natural gas pipelines to a halt.

Norman Bay said he’ll leave the Federal Energy Regulatory Commission effective Feb. 3. His announcement followed President Donald Trump’s decision to replace him as the agency’s chairman with his fellow commissioner, Cheryl LaFleur.
