Support for same-sex marriage In June 2011, Mehlman lobbied Republican members of the New York state legislature to support the legalization of same-sex marriage in New York and reached out to conservative donors and operatives. Mehlman often spoke with undecided GOP senators, including three of the four who eventually voted in favor of the bill. Mehlman told GOP senators that legalizing same-sex marriage aligned with Republican interests and principles. He emphasized that polls showed a significant shift toward voter support of same-sex marriage. Mehlman was honored in
Out Magazine 2011's Out100 list partially because of his work on the campaign. Mehlman has been active in Maryland, New Hampshire and Washington State, helping to raise almost $3 million for these campaigns between August 2010 (when he came out) and March 2012. He continued to campaign for same-sex marriage, before
United States v. Windsor, the 2013
United States Supreme Court decision which held that same-sex marriage is constitutional, by aiming to show GOP leaders why same-sex marriage "is consistent with Republican and conservative principles", and speaking on that topic throughout the country. In January 2013, also before
United States v. Windsor, Mehlman spoke with political activist David Kochel in Iowa about how supporting same-sex marriage is a conservative value. He stated that, "I'm a conservative because I believe in more freedom and I believe in less government. I think that we are endowed by our Creator, not by politicians, not by government, not by bureaucrats, with inalienable rights, including the pursuit of happiness. If you believe that, what could be more central to the pursuit of happiness than choosing the person that you love, that you have the right to marry?" In February 2013, Mehlman helped organize an
amicus curiae brief to the Supreme Court in the case of
California Proposition 8 signed by dozens of prominent socially moderate Republicans, including
Jon Huntsman, Jr.,
Meg Whitman,
Ken Duberstein,
Ileana Ros-Lehtinen, and others, explaining that they supported a Constitutional right to same-sex marriage. According to the
New York Times, Ken Mehlman spent "months in quiet conversations with fellow Republicans to gather signatures for the brief." "We are trying to say to the court that we are judicial and political conservatives, and it is consistent with our values and philosophy for you to overturn Proposition 8," said Ken Mehlman according to the New York Times report. In November 2013, Mehlman launched a non-profit organization called Project Right Side focused on convincing more Republicans to support marriage equality. The organization also conducts research and analysis in an effort to improve political conditions for LGBTQ issues. He stated that "Conservatives don't need to change core convictions to embrace the growing support for equal rights for gay Americans. It is sufficient to recognize the inherent conservatism in citizens' desire to marry, to be judged on their work, and not to be singled out for higher taxes or bullying at school. These objectives can be achieved while also protecting religious liberty, as demonstrated by states enacting civil marriage with exemptions for religious institutions." In February 2014, Mehlman was a keynote speaker at the first campus-wide
Harvard LGBTQ conference on the 45th anniversary of the Stonewall Riots where he was interviewed by
Baruch Shemtov. He spoke during the closing remarks of the conference, stating "there's nothing more powerful than coming out and being who you are."
Don't Ask, Don't Tell legislation Mehlman supported the repeal of the "
Don't ask, don't tell" military policy introduced during
President Bill Clinton's tenure. In 2010, Mehlman lobbied ten U.S. Senators to repeal the policy. In July 2019, Mehlman filed an amicus brief, joined by close to three dozen other Republican leaders, arguing in support of the rights of LGBT people in the workplace. The brief argued that the Civil Rights Act of 1964 explicitly prohibits discrimination against gay men, lesbians and transgender people in the workplace due to language in the law that prohibits discrimination on the basis of sex. In addition, Mehlman wrote an op-ed for
The New York Times outlining his reasons for believing that the fight for gay rights upholds the Republican values of economic freedom and personal liberty. In the piece, Mehlman writes that firing an employee because of their sexual orientation or
gender identity is "... unethical and un-American, and the Supreme Court has the opportunity to read the clear language of Title VII [of the Civil Rights Act] and affirm that it is illegal." ==Personal life==
