Like American football player Colin Kaepernick before her, Ms Rapinoe knelt as a protest against discrimination in the USA.
This caused venomous attacks on Ms Rapinoe by Donald Trump and Rupert Murdoch. The United States soccer bosses, cowards like their American football counterparts, reacted by banning anti-racist protests.
Recently, the international football (soccer) association FIFA decided that footballers should not be punished for kneeling against racist police violence.
And United States soccer bosses may follow suit.
This 9 June 2020 video from the USA is called US Soccer considers rescinding the kneeling ban.

Men’s Football: Mikel Arteta supports Arsenal players in protesting against racial injustice
The Gunners wore t-shirts with a variety of messages on them, such as “I can’t breathe”, “My skin is not a crime” and “I’m not black but I stand with you”, in support of the protests going on around the world.
They also took a knee before kick-off, a symbolic way to show support, popularised by American football player Colin Kaepernick, which is also being reviewed by Olympic organisers.
