Chelsea Clinton, the daughter of former President Bill Clinton and Democratic presidential front-runner Hillary Rodham Clinton, says that she helped her mom evolve on marriage equality.

Clinton appeared Thursday on Ellen DeGeneres' daytime talk show, where she discussed how she became involved in the issue.

“When I got married in 2010 to my best friend, it just crystallized so fundamentally to me that everyone should be allowed to marry their best friend,” Clinton said. “And so I joined the equal marriage fight in New York, and we got equal marriage in New York in 2011.”

“I am just so proud that our country is the country that I want my daughter to grow up in so she can marry whoever she wants to marry.”

Hillary Clinton was the last in her family to endorse marriage equality, which she did in 2013 after she had left her post at the State Department.

Chelsea Clinton told DeGeneres that she “absolutely” pushed her mom on the issue.
