The head of US Soccer was interrupted by boos and chants of “Equal pay!” during a ceremony for the US women’s World Cup champions in Manhattan on Wednesday.

Carlos Cordeiro, the president of the US Soccer Federation, was in the middle of congratulating the team and boasting about how the country has invested more in women’s soccer than any other nation.

“And we will continue to invest –” Cordeiro said, before the crowd began booing and chanting, “Equal pay!” “Pay them!” and “Pay gap!”

Some irate spectators were screaming “Get off the stage!”

After a few seconds, he continued, “We will continue to invest more in women’s soccer than any country in the world and we will continue to encourage others, including our friends at FIFA, to do the same.”

“We believe that at US Soccer all female athletes deserve fair and equitable pay. And together I believe we can get this done,” Cordeiro added, “because as this team has taught us, being the greatest isn’t just about how you play on the field, it’s about what you stand for off the field.”

The issue of equal pay among male and female athletes has been the running theme of the women’s World Cup — with the US national team leading the charge.

After each member of the squad received a key to the city, co-captain Megan Rapinoe came to Cordeiro’s defense.

“I’m going to stick my neck out there a little bit, I’m going to endorse Carlos. I think he’s with us. I think he’s on the right side of things. I think he’s going to make things right,” she told the crowd in her speech.

Then, she added, “We look forward to holding those feet to the fire.”

Some fans among the nearly 3,800 who were lucky enough to score a ticket to the City Hall ceremony weren’t buying Cordeiro’s promise.

“F–k him!” said Ali Sullivan, 25, who tried to storm the stage to confront the soccer bigwig but was escorted away by police. “He’s gonna come here, and he’s going to be like, ‘Oh, I’m so proud of these women, they did so much, blah blah blah.’ You publicly tell them that they’re not worth more than the guys!”

Dayna Halprin, 29, carried a sign reading “OK. Now Pay Them” to the event.

“It came across as lip service!” she said about Cordeiro’s comments. “This is a lot for young athletes, particularly young queer athletes.”
