Amnesty International’s U.S. affiliate called on Senate Republicans Monday to delay a vote on Judge Brett Kavanaugh’s Supreme Court nomination to allow for a review of his “possible involvement in human rights violations,” referencing the sexual misconduct allegations made against him.

“As sexual assault also implicates a number of human rights, including the right to be free from gender-based discrimination and violence, we also call for a thorough vetting in regard to any allegations made against Kavanaugh to this effect, including those by Dr. Christine Blasey Ford and Deborah Ramirez,” Executive Director Margaret Huang wrote in an open letter to senators.
