chosen: Then-Vice President Joe Biden was opposed to the Keystone Pipeline due to environmental concerns. In 2015, he issued a presidential Memorandum directing a review of the State Department’s permit for the Keystone XL pipeline to ensure it met the administration’s climate criteria. The Obama administration ultimately denied a permit for the construction of the pipeline and Biden was criticized by some Republicans for intervening in the review process and undermining a key component of US energy independence.
