The pipeline was a prominent issue in the 2014 United States mid-term elections, and after Republicans gained control of the Senate that year, the project was revived. The following year, President Obama said in his speech announcing the rejection of the pipeline on November 6, 2015, that Keystone XL had taken on symbolic importance, "for years, the Keystone pipeline has occupied what I, frankly, consider an overinflated role in our political discourse. It became a symbol too often used as a campaign cudgel by both parties rather than a serious policy matter." He went on to state that "approving this project would have undercut United States' global leadership" on climate change.
