Buffett has given his support to the Keystone XL for years. This is just the latest time he spoke of it.

But Buffett — an Obama supporter whose name has been used by the White House to sell a plan to increase taxes on the rich — steered clear of criticizing the president.
“I don’t think that issue is done with yet,” Buffett said when asked whether he was disappointed in President Obama’s decision to reject a key permit for the project in January.
Same old Buffett bs. Obama's had over 6 years to approve the pipeline, while Buffett blows smoke.
