Only four countries in Latin America legalized same-sex marriage -- but soon, there may be a fifth.

On Tuesday, Mexican President Enrique Pena Nieto declared his proposition to make gay marriage legal in his country.

According to CBS News, Pena Nieto claimed he wanted “to recognize as a human right that people can enter into marriage without any kind of discrimination,” desiring to change Article 4 of the country’s constitution to match the Supreme Court’s opinion.

The president’s Twitter page, as well as that of other Mexican government accounts, had their pages altered to have rainbow colors following Pena Nieto’s announcement.

Congress requires a two-thirds majority vote to amend the constitution. According to LGBTQ Nation, Pena Nieto’s allies and party have over half of the seats, leading up to a potential ratification by the majority of states until finally requiring a signature by Pena Nieto.

Pena Nieto’s announcement had perfect timing – his Tuesday announcement came on the International Day Against Homophobia, Transphobia and Biphobia, a day focused on celebration of sexual and gender identities.
