done in 1993. On November 6, 2012, Minnesota became the first state to vote down a proposed constitutional amendment banning same-sex marriage. The amendment failed with a 53% to 47% vote. All state constitutional and statutory bans on same-sex marriage were declared unconstitutional in June 2015 in Obergefell v. Hodges. Public opinion A May 2018 Gallup poll found that 67% of Americans supported same-sex marriage. A March 2014 public opinion poll by The Washington Post/ABC News showed support for same-sex marriage at 59% among Americans, and a February 2014 New York Times/CBS News opinion poll showed 56% support for same-sex marriage. A November 2012 Gallup poll indicated 61% support for gays and lesbians being allowed to adopt children. Discrimination protections Anti-discrimination laws U.S. federal law does not explicitly include protections against discrimination on the basis of sexual orientation or gender identity. In June 2020, the U.S. Supreme Court ruled that sexual orientation and gender identity are included under "sex" as a prohibited ground of employment discrimination in the Civil Rights Act of 1964. The ruling may impact other federal civil rights barring sex discrimination in education, health care, housing, and financial credit. Explicit and comprehensive anti-discrimination protections based on sexual orientation and gender identity are considered by the United States Congress under the Equality Act, which "was passed in the House by a bipartisan vote of 236-173 on May 17, 2019." As of July 27, 2020, the bill remains in the Senate. Employment Employment discrimination refers to discriminatory employment practices such as bias in hiring, promotion, job assignment, termination, and compensation, and various types of harassment. There is no federal statute explicitly addressing employment discrimination based on sexual orientation or gender identity. However, in June 2020, the U.S. Supreme Court ruled that sexual orientation and gender identity are included under "sex" as a prohibited ground of employment discrimination in the Civil Rights Act of 1964. This effectively means that in the U.S., no employer can fire an employee on the basis of sexual orientation or gender identity. Twenty-four states, the District of Columbia, Puerto Rico, Guam, and over 140 cities and counties have enacted bans on discrimination based on sexual orientation and/or sexual identity. Additionally, some states have laws or regulations that ban discrimination based on gender identity and/or sexual orientation in public employment only. Presidents have also established certain protections for some employees of the federal government by executive
