The 28 players on the U.S. women's national soccer team sued the United States Soccer Federation on Friday, claiming gender discrimination.

The two sides long have been involved in a dispute over working conditions and pay that became public in 2016 when five players filed a wage discrimination complaint with the Equal Employment Opportunity Commission.

The team is scheduled to defend its World Cup title beginning in June in France.

The lawsuit was filed in U.S. District Court in Los Angeles, and the filing shows the team is accusing the federation of "institutionalized gender discrimination."

The players contend their male counterparts receiver better pay and working conditions that include training, coaching, medical care, travel accommodations and game scheduling.

The players have asked for their lawsuit to be certified as a class-action case and want it to include any woman who played on the national team since Feb. 4, 2015. They are seeking back pay and damages.
