"It's law. It was settled in the Supreme Court. I mean, it's done." This somewhat contrasted with a previous statement he made in June 2015, after Obergefell v. Hodges, in which he said he's personally for "traditional marriage" and that he believed same-sex marriage should be left to the states. In that same statement, however, Trump admitted that overturning Obergefell is not realistic. Several of his federal appointments have also, subsequently, announced they will uphold same-sex marriage and enforce the Supreme Court ruling, while still being personally against same-sex marriage, namely Attorney General Jeff Sessions and Secretary of Education Betsy DeVos. Former presidents Bill Clinton, Jimmy Carter, and Barack Obama, former vice presidents Dick Cheney, Al Gore, Walter Mondale, and Joe Biden have voiced their support for same-sex marriage, as have former first ladies Laura Bush, Hillary Clinton, Michelle Obama, and Nancy Reagan. Former President George H. W.

In an interview on The O'Reilly Factor in August 2010, when Glenn Beck was asked if he "believe(s) that gay marriage is a threat to [this] country in any way", he stated, "No I don't. ...
