WASHINGTON, Feb 24 (Reuters) - Republican U.S. President

Donald Trump said on Monday he wanted the Keystone XL pipeline,

which was opposed for years by activists fighting against

climate change, to be built.

The pipeline was proposed in 2008 to bring oil from

Canada's Western tar sands to U.S. refiners and was halted in

2021 by owner TC Energy Corp ( TRP ) after Democratic former

President Joe Biden revoked a key permit needed for a U.S.

stretch of the project.

"We want the Keystone XL Pipeline built," Trump said in a

social media post on Monday.
