In response to the brutal repression of the protests in Iran, the US wants to throw the country out of the UN Commission on Women's Rights.
US Vice President Kamala Harris said on Wednesday that the US would work with its partners to remove Iran from the body.
"The US believes that no nation that systematically disregards the rights of women and girls should have a role in any international or UN body charged with protecting those same rights," Harris said.
Iran has "proven by its denial of women's rights and its brutal actions against its own population that the country is unsuitable for participation in this commission".
Iran's presence alone discredits the integrity and work of the body.
Meanwhile in New York on Wednesday the members of the UN Security Council discussed the situation in Iran at the initiative of the USA.
The American ambassador to the UN, Linda Thomas-Greenfield, pledged her full support to the women in Iran.
However, the path will not be easy: "Change will not come overnight." But the current situation in Iran is important for women worldwide.
"Women are counting on us to do the right thing."
The trigger for the system-critical mass protests in Iran was the death of the 22-year-old Iranian Kurd Mahsa Amini.
The vice squad arrested her for allegedly violating Islamic dress codes.
The woman died in police custody in mid-September.
Tens of thousands of people have been demonstrating against the Islamic Republic's repressive policies and authoritarian course for more than six weeks.
According to human rights activists, more than 280 people were killed and more than 14,000 arrested.
