Serena Williams is a fan of the U.S. Women's soccer team fighting for equal pay.
Players filed a gender discrimination lawsuit against U.S. Soccer, noting that pay, medical treatment and transportation have not been equal to what their counterparts on the men's team receive.
"I don't follow soccer as much," she told reporters in Indian Wells, according to beIN Sports. "I do know that the pay discrepancy is ludicrous. It's a battle, it's a fight."
In the lawsuit, the team alleges the United States Soccer Federation "has utterly failed to promote gender equality," and that members of the women's team are not treated equally to the men.
