Last week, co-hosts Australia and New Zealand wrote to FIFA seeking urgent clarification after the Guardian reported Visit Saudi will be named as a major sponsor of the July 20th to August 20th tournament.

"US Soccer strongly supports human rights and equity for all and believes in the power of our sport to have a positive impact," the USSF said in a statement to the Athletic.

"While we cannot control how other organisations manage sponsorship selections for the tournaments we compete in, we can voice our concerns and will continue to support our players."

The United States are FIFA's top-ranked team and won the last two editions of the World Cup.

The Guardian report triggered outrage in both host countries, with human rights activists and sportswomen saying Saudi sponsorship would be at odds with the tournament's messaging on the empowerment of women and girls.

Saudi Arabia Crown Prince Mohammed bin Salman has introduced reforms allowing women greater control over their lives in recent years but men still retain a tight grip on power in the kingdom.

Veteran US forward Alex Morgan (33), who won the World Cup in 2015 and 2019, described the potential sponsorship as "bizarre".

"Morally, it just doesn't make sense," Morgan told reporters on Wednesday. "I just don't understand it ... I really hope that FIFA does the right thing."
