Billionaire Warren Buffett supports building the Keystone XL pipeline that TransCanada wants to build to carry Canadian oil south across the Great Plains to connect to Gulf Coast refineries.
Buffett was asked about the project that would cross Nebraska Monday on Fox Business Network.
Buffett says he's not an expert on the project, but he thinks it generally makes sense to build the pipeline.
Last week, TransCanada reapplied for a permit to build the pipeline after changing the route through Nebraska to avoid the environmentally sensitive Sandhills region.
State Department approval is needed because the $7 billion pipeline would cross a U.S. border before crossing Montana, South Dakota, Nebraska, Kansas and Oklahoma. TransCanada has also proposed connecting the pipeline to the Bakken oil field in North Dakota.
