(Reuters) - U.S. President Donald Trump will announce the approval of the Keystone XL oil pipeline at the White House on Friday, alongside the chief executive officer of builder TransCanada Corp, according to a senior administration official.
The pipeline linking Canadian oil sands to U.S. refiners had been blocked by former President Barack Obama, who said the pipeline would do nothing to reduce fuel prices for U.S. motorists and would contribute emissions linked to global warming.
