CHICAGO — U.S. soccer star Megan Rapinoe knelt during the national anthem before the Seattle Reign’s game against the Chicago Red Stars “in a little nod” to NFL quarterback Colin Kaepernick.

“It’s the least I can do. Keep the conversation going,” Rapinoe tweeted about her actions in protest of racial injustice and minority oppression.

Since coming out in 2012, Rapinoe has been a devoted advocate for LGBT rights and has worked with the Gay, Lesbian & Straight Education Network (GLSEN) and other organizations.

Rapinoe also has been vocal about pay equity, and was among five national team players who lent their names to a complaint filed with the Equal Employment Opportunity Commission alleging wage discrimination. The players claim that members of the team make in some cases up to four times less than their male national team counterparts.
