WASHINGTON — The departure of Scott Pruitt, the scandal-plagued former head of the Environmental Protection Agency, means that the agency will be led in the coming months by Mr. Pruitt’s deputy, Andrew Wheeler, a former coal lobbyist who shares Mr. Pruitt’s zeal to undo environmental regulations.

But unlike Mr. Pruitt — who had come to Washington as an outsider and aspiring politician, only to get caught up in a swirl of controversy over his costly first-class travel and security spending — Mr. Wheeler is viewed as a consummate Washington insider who avoids the limelight and has spent years effectively navigating the rules.
