Sam Smith performs at White House as president Joe Biden signs Respect for Marriage Act

Hollywood star Sam Smith performed at the White House as Americans celebrated a landmark agreement on Tuesday.

Respect for Marriage Act guarantees same-sex and interracial married  couples the same rights as legally married spouses in all 50 US states.

The signing of the federal law comes after Obergefell v Hodges and Loving v Virginia.

Cyndi told the crowd: "This time, love wins" as she sang 'True Colours'.
