Senate Republicans have announced plans to introduce legislation allowing Congress to approve the Keystone XL oil pipeline, despite President Obama’s rejection of the controversial project. An analysis by the Public Campaign Action Fund and 350.org found that the bill’s 44 co-sponsors have received a combined $22.3 million in campaign contributions from the oil and gas industry since 1989. One Democrat has joined the Republican effort: Joe Manchin of West Virginia. TransCanada, the company behind the $7 billion pipeline, spent $1.33 million on lobbying last year.
