—Sen. Ernst has been a featured speaker numerous times at the Family Leadership Summit organized by anti-LGBTQ group The Family Leader, which is affiliated with the Family Research Council, labeled a hate group by the Southern Poverty Law Center (SPLC). The group gained national prominence for its “The Marriage Vow” pledge, which it asked 2012 presidential hopefuls to sign, vowing to oppose same-sex marriage and civil unions, as well as same-sex and single parenting, and to allow for anti-LGBTQ discrimination on the basis of religious beliefs. The vow also included language condemning judges it said had “personally rejected heterosexuality and monogamy,” and argued for separating LGB soldiers from their fellow same-sex servicemembers in “restrooms, showers, barracks, tents, etc.”

—Voted against an amendment which sought to protect LGBTQ students from discrimination in public schools, grades K-12.

—Released statement criticizing the Obergefell v. Hodges ruling legalizing marriage equality nationwide, saying she was “disappointed by the Supreme Court’s decision and its failure to recognize the freedom of our states to make their own decisions about their respective marriage laws…. While it is my personal belief that marriage is between one man and one woman, I maintain that this is an issue best handled at the state level,” she added.

—Voted against amendment to provide benefits to the same-sex spouses of veterans and their children in states where their marriages weren’t recognized.

—Voted against an amendment to ensure same-sex spouses had equal access to Social Security and veterans benefits.
