In Chile on Sunday, Senator Fulvio Rossi announced his plan to sponsor a marriage equality bill.

His bill is expected to encounter opposition from religious leaders, conservative president Sebastian Pinera, and other members of Congress, according to Reuters Canada. Yet just last month, Argentina, a border country of Chile, became the first country in Catholic Latin America to legalize same-sex marriage.

According to Reuters Canada, Rossi told reporters, “This is a project that I will present … and I am also calling on the Church to be more welcoming, and I say that as part of the Church.”
