Keystone XL

"The four (spills) were caused by issues related to the original design, manufacturing of the pipe, or construction of the pipeline," a report by the Government Accountability Office found.

The Kentucky senator accused the Biden administration of harming jobs by deciding to revoke the pipeline's permit.

Legal action backed by attorneys general in 21 states challenges the president's executive order revoking the permit.

The president's decision to choose the Kremlin over Keystone is a slap in the face to the 11,000 American workers whose good-paying jobs vanished on Inauguration Day.

Though no mode of oil transport is perfect, pipelines have proven to be the safest and most environmentally friendly way to carry oil.

"I wish he hadn't done that on the first day," said AFL-CIO President Richard Trumka. "It did and will cost us jobs in the process."

Senator Joe Manchin voted in favor of the pipeline as he snubbed the president's block on construction.

The debate over the Keystone XL pipeline had its day.

Of all the executive orders Biden has signed during his first week in office, a third have been reversals of Trump-era policies.

"We are deeply disturbed...This is a gut punch for the Canadian and Alberta economies," Jason Kenney said Sunday.

President Joe Biden suspended the permit for the Keystone XL pipeline project on Wednesday, a controversial project that would have shipped hundreds of thousands of barrels of carbon-heavy oil from Canada to the U.S. daily.

Reports indicate Biden will rescind the permit for the controversial pipeline on his first day in office.

"I wish I could say I was shocked, but a major spill from the Keystone pipeline is exactly what multiple experts predicted would happen," said a Greenpeace USA senior research specialist.

Nebraska's Public Service Commission cleared the way for the controversial project on Monday. Here's everything you need to know.

Trump on Monday false claimed during remarks to business leaders in Tokyo that construction for the controversial pipeline is underway, even though the project hasn't found buyers yet.

The pipeline had been blocked by Obama, who said it would do nothing to reduce fuel prices for U.S. motorists and would contribute to emissions linked to global warming.

The move would mark the beginning of a process that could be lengthy. Approvals are needed from state regulators, and the project could face legal challenges.

Protesters were set to gather in a number of U.S. cities on Wednesday, a day after the U.S. Army said in a legal filing it planned to cancel an environmental study and grant the final easement needed to complete the Dakota pipeline.

Paul Ryan and Donald Trump used to feud. They don't any longer.

While oil producers in Canada and North Dakota are expected to benefit from a quicker route for crude oil to U.S. Gulf Coast refiners, a revival of the projects would mark a bitter defeat for Native American tribes and climate activists.

With a global climate change summit looming, so are fights over Obama proposals.

The project, he said, would have done less than promised for the U.S. economy, and would "undercut" the country's position as a global leader in fighting climate change.

"The pipeline would not make a meaningful long-term contribution to our economy," the president said.

The decision is expected to lead to the project's rejection by the Obama administration.

The president has increasingly signaled the $8 billion pipeline may not be approved.

A delay would almost certainly hand the decision for the $8 billion project to a future president.

She called the pipeline a "distraction."

The controversial project now awaits an administration decision on whether to permit or deny it.

The world's third largest oil reservoir may never see the light of day.

The temporary injunction was prompted by a lawsuit from 70 landowners who don't want the pipeline on their property.
