Defendants in the Houston lawsuit are U.S. Secretary of State John Kerry, Attorney General Loretta Lynch, U.S. Homeland Security Secretary Jeh Johnson and Sally Jewell, Secretary of the Department of Interior.

The Keystone XL was designed to link existing pipeline networks in Canada and the United States to bring crude from Alberta and North Dakota to refineries in Illinois and, eventually, the Gulf of Mexico coast.
