Despite growing nationwide protests, rising costs and an Obama administration decision to block continued construction until additional environmental studies have been completed, Energy Transfer CEO Kelcy Warren is "100 percent" confident that the Dakota Access pipeline will be built during Donald Trump's presidency.

The 1886 km, 30 inch diameter pipeline, is 84 percent completed, with all but 1000 more feet to cover.

Native Americans and environmentalists say the pipeline could threaten the water supply of millions and disrespect sacred lands.

Obama administration officials have requested that Energy Transfer voluntarily stop construction underneath Lake Oahe. Yet there is no readiness to change course, particularly since the company has received all necessary permits from the Army Corps of Engineers.

Warren donated $103,000 to Trump’s campaign and Trump has minor investments in Energy Transfer. When asked if he has ever spoken to Donald Trump about the pipeline, Warren said that he 'has never met the man."
