United States first daughter Ivanka Trump waded into the debate over Serena Williams’s lack of a seeding at the French Open, tweeting that the women’s tour needed to change its rules for players that take maternity leave. Williams was world number one before leaving the tour last year to have a baby but the 23-time grand slam champion enters Roland Garros ranked 453rd. The 3-time French Open champion was not granted a seed by tournament organisers, triggering criticism from women’s groups and tennis pundits.

“This is ridiculous. @SerenaWilliams is a formidable athlete (best ever!) and loving new mother,” Ivanka Trump, daughter of U.S. President Donald Trump, wrote on Twitter. “No person should ever be penalized professionally for having a child! The #WTA should change this rule immediately. #FrenchOpen.”
