A Canadian government official familiar with the matter says Prime Minister Mark Carney raised the prospect of reviving the contentious Keystone XL pipeline project during his White House meeting with U.S. President Donald Trump this week. A Canadian company pulled the plug on it four years ago after the Canadian government failed to persuade then President Joe Biden to reverse his cancellation of its permit on the day he took office. It was to transport crude from the oil sand fields of western Canada to Steele City, Nebraska. President Donald Trump previously revived the long-delayed project during his first term after it had stalled under the Obama administration. The Canadian government official says Trump was receptive to the idea.
