'A Day Without a Woman' rally draws crowd of anti-Trump protesters

A sea of protesters in red filled New York's Washington Square Park on Wednesday afternoon as they rallied around a new addition to this year's International Women's Day -- "A Day Without a Woman."

While the Facebook event for the Washington Square Park rally lists International Women's Strike NYC as the official hosts, most of the hundreds in attendance held signs that referenced the "A Day Without a Woman" campaign. The "A Day Without a Woman" movement was initiated by organizers of the Jan. 21 Women's March on Washington, an event that spurred global rallies in protest of then-newly elected President Trump.

According to an official statement, 13 Women's March organizers and supporters were arrested by the New York City Police Department in an act of civil disobedience at an additional rally in Central Park earlier on Wednesday. After they staged a peaceful rally, the group marched to Trump International Hotel and Towers in Columbus Circle with the intention of linking arms and presenting a line in front of the building. The 13 arrested were reportedly taken into custody under the grounds of disorderly conduct.

In the same week the House GOP unveiled their American Health Care Act -- legislation that would defund Planned Parenthood if enacted -- rally attendees held signs with messages like "Claim sexual freedom" and "Stand with Planned Parenthood." The rally is set to conclude with a march to New York's Zuccotti Park.

The official "A Day Without a Woman" website listed multiple ways people could participate in Wednesday's events, including women taking the day off from paid and unpaid work, only spending money at women and minority-owned businesses for the day and standing in solidarity by wearing the color red as a symbol of "revolutionary love and sacrifice."
