Jamie Lee Curtis, Chelsea Handler, Samantha Bee, Alyssa Milano, and more major Hollywood women joined left-wing activist organizations Planned Parenthood and NARAL to push an anti-Brett Kavanaugh “walkout” Monday in solidarity with his accuser Judge Brett Kavanaugh.

Hollywood celebrities and politicians wore black as a show of solidarity with Kavanaugh’s accuser, Christine Blasey Ford.

Ford accused Kavanaugh groping and attempting to remove her clothing during a house party when he was 17-years-old.

On Monday, Kavanaugh released a letter stating that he “will not be intimidated into withdrawing.”

“We believe Dr. Christie Blasey Ford & we stand with her. Kavanaugh should be disqualified from the Supreme Court—& the GOP must stop bullying her. Join us in solidarity by wearing black & walking out of work/school/home on Monday at 1 pm ET + posting a photo w/ BelieveSurvivors,” NARAL, a pro-abortion group, tweeted over the weekend to promote the “walkout.”
