A Republican congressman attended his son's same-sex wedding just days after voting against protections for same-sex marriage

The Respect for Marriage Act would codify same-sex marriage into law if passed in the Senate and signed by the president.

The lawmaker attended his son's wedding three days later.

The congressman's son told NBC News that his father was at his wedding on Friday. The groom's name is not being published by Insider.

Thompson's new son-in-law will be welcomed into the family by the Thompsons, according to a Thompson's spokesman.

Madison Stone said that the congressman and his wife were thrilled to attend and celebrate their son's marriage on Friday night.

The press secretary for Thompson told the Centre Daily Times that the Respect for Marriage Act was nothing more than a political stunt by Democrats who have failed to address historic inflation and out of control prices at gas.

Thompson's son's wedding was reported on in a Thursday article by the website.

47 Republicans joined all 220 Democrats in voting for the Respect for Marriage Act in the House of Representatives.

At least 10 Republicans need to join all 50 Democrats in order for the legislation to pass in the evenly split Senate. There are five GOP senators who are willing to support the legislation.

The 1996 Defense of Marriage Act defined marriage as between a man and a woman. The law remained on the books even after the definition was struck down. Any state actor who fails to give full effect to an out of state marriage on the basis of sex, race, gender, or national origin would be barred from doing so.

Democrats immediately called for codifying same-sex marriage protections after the Supreme Court ruled against federal abortion rights. While Justice Samuel Alito's majority opinion said the case should not affect any other rights, conservative Justice Clarence Thomas wrote a concurring opinion suggesting that the court "reconsider" certain landmark decisions.
