TransCanada's proposed Keystone XL Pipeline would transport oil sands crude from Canada and shale oil produced in North Dakota and Montana to a market hub in Nebraska for further delivery to Gulf Coast refineries. The pipeline would consist of 875 miles of 36-inch pipe with the capacity to transport 830,000 barrels per day. The Congressional Research Service (CRS) receives frequent requests for congressional votes taken on Keystone XL Pipeline legislation. This report provides roll call vote data on Keystone XL Pipeline legislation identified by CRS using CQ.com's Roll Call Vote Report database as well as the Congress.gov legislative database. Roll call votes listed in the tables are broken down by chamber, Congress, and type of legislation-substantive votes (i.e., votes on amendments or passage of bills) versus procedural votes (e.g., votes to recommit the bill to a committee or to provide for the consideration of a bill). Votes are also listed in chronological order for each Congress.
