in 2014. Despite his opposition to partial-birth abortion, Clyburn is regarded as pro-abortion rights, as shown by his high ratings from Planned Parenthood and NARAL Pro-Choice America and low rating from the National Right to Life Committee. But at the height of national polarization after the Supreme Court's intention to overturn Roe v.

Clyburn pushed for a 2010 contract to convert plutonium from old weapons into nuclear fuel. Organizations such as the League of Conservation Voters and Defenders of Wildlife have viewed Clyburn favorably, but he angered environmentalists when he proposed building a
