NEW: President Trump says the Alaska LNG pipeline will deliver nearly 4 billion cubic feet of natural gas per day as he announces a massive new U.S. energy investment. "The United States is already the largest natural gas producer and exporter in the world, and this pipeline will help us expand those exports even further." The president says the project is part of agreements with South Korea that include up to $200 billion in investment and eight new large-scale nuclear power plants. Trump says he's been hearing about an Alaska pipeline for five decades. Now he's putting it at the center of the new energy push. ▻
