Gauff had been urging people to bring a change and did so at a peaceful Florida rally in Delray Beach, her hometown making a speech.
She urged people to register to vote and help bring this change to fruition which prompted a reply from the Belgian.
"Thank you for being a girl that my daughter will learn from and look up to. I promise that we will keep on teaching our kids the right thing to do so that they can pass it on too. It all starts at home," said Clijsters on Twitter.
She has also been praised by American tennis legend Chris Evert in recent times calling her a 'future leader, role model and activist'.
