The US Senate has approved a groundbreaking bill to protect same-sex and interracial marriage in federal law on 29 November.
Same-sex marriage was legalised in 2015 when the Supreme Court ruled that a previous law defining marriage as between a man and a woman was unconstitutional.
There has been a movement within the US to enshrine decisions in federal law following the overturning of Roe v. Wade. Roe v.
Wade established access to abortion as a constitutional right, but was overturned by the conservative majority in the Supreme Court.
