After hours of floor debate and votes on dozens of amendments over more than two weeks, today the U.S. Senate approved a bill to force construction of the Keystone XL pipeline. Nine Democrats joined all the Republicans present to pass the final bill by 62 votes to 36 (roll call). Iowa’s Senators Chuck Grassley and Joni Ernst have long supported Keystone XL, and Ernst possibly owes as much as any member of the Senate to campaign spending by the Koch brothers, who stand to profit from more tar sands oil extraction in Canada.
The Keystone XL bill now goes back to the U.S. House, which will surely send it to President Barack Obama. (All four Iowans supported the pipeline bill that cleared the House earlier this month.) A White House spokesman repeated today that the president intends to veto the current bill.
Before today’s vote on final passage, senators rejected more than a dozen amendments to the Keystone XL bill. You can find all the roll calls here. Democrats offered most of the defeated amendments, which went down primarily along party lines. For instance, Grassley and Ernst helped their GOP colleagues reject Sheldon Whitehouse’s amendment, which was designed to “require campaign finance disclosures from companies benefitting from the Alberta oil sands.” Other defeated Democratic amendments would have further studied potential safety problems and threats to public health associated with the Keystone XL pipeline, allowed permitting agencies “to consider new circumstances and new information,” or delayed the effective date of the bill until the President could rule out “certain negative impacts” from its construction.
In what may be the first Senate vote where Grassley and Ernst landed on opposite sides, Grassley was one of just three GOP senators to support Heidi Heitkamp’s amendment that would have extended renewable energy tax credits. Ernst was among the 51 Republicans who voted against that amendment, which would benefit Iowa’s wind power industry. Both Grassley and Ernst voted against Bernie Sanders’ effort to expand incentives for installing solar power and Tom Udall’s amendment on establishing a federal renewable electricity standard.
A few Republican amendments also fell short of the 60 votes needed for passage during the Keystone XL debate. Without Democratic votes, support from Grassley, Ernst, and most of the GOP caucus wasn’t enough to win approval of Ted Cruz’s amendment promoting crude oil exports, Jerry Moran’s effort to “delist the lesser prairie-chicken as a threatened species,” or Lisa Murkowski’s amendment, which would “free up areas like ANWR [Alaska National Wildlife Refuge] and others that have been designated by the federal government as wilderness regions to potential drilling.” Yesterday and today, Grassley and Ernst helped the Republican majority either to reject or to table a series of amendments related to climate change. Puneet Kollipara and David Malakoff described those amendments and votes in this Science magazine article.
During Senate sessions last week, Grassley and Ernst voted for language stating that climate change is “real” and “not a hoax” but against various statements indicating that human activity contributes to climate change.
