The World Cup winner pledged her support for the tennis great, saying she will continue the battle for equal pay for the rest of her life
United States forward Megan Rapinoe has echoed Serena Williams' comments on equal pay amid the Women's World Cup winners' ongoing fight for parity with the men's team.
"You know what? I'm gonna fight for equal pay every day, for myself, for my team, and for every single person out there," said Rapinoe.
"Man, woman, immigrant, US citizen, person of colour, whatever it may be. 'Equal pay,' as the great Serena Williams said, 'til I'm in my grave'."
Rapinoe, whose partner is basketball player Sue Bird, also defended her previous comments on Trump when asked what she would say to her fans who support the president and believe she should go to the White House.
She added: "I would try to share our message. Do you believe that all people are created equal? Do you believe that equal pay should be mandated?
"Do you believe that everyone should have health care? Do you believe that we should treat everyone with respect? Those are the basics of what we're talking about.
"I understand people feel upset or uncomfortable. There's feelings of disrespect about the anthem protest or things that I've said in the past. Ultimately, I am here, open and honest.
"I've admitted mistakes. I will continue to do that. I'll continue to be vulnerable and be honest and open and have that conversation."
