International Desk: History is the highest court in the United States. For the first time, a black woman judge has been appointed to the country's Supreme Court. Ketanji Brown Jackson, the first black woman judge of the Supreme Court, was sworn in on Thursday. Democratic President Joe Biden has broken the 233-year dominance of white men in the US Supreme Court by appointing a 51-year-old African-American black woman as a judge, CNN reports. Jackson's appointment to the Supreme Court is one of the milestones. But that won't change the Conservative majority in the Supreme Court. The court has come under fire for its recent ruling to extend the right to bear arms and abolish the right to abortion in the country due to the conservative majority. Four judges in the nine-member U.S. court are now women. It has become the most diverse bench in history. Although they have all studied in elite law schools like Harvard or Yale. On April 6, 52 votes were cast in favor of this African-American woman in the US Senate. And 48 votes were cast against him. With more than five votes, Ketanji Brown Jackson is now the first African-American or the first black woman judge in the United States Supreme Court. U.S. Vice President Kamala Harris presided over the Senate vote, Reuters reported. Many Republican members voted in favor of Ketanji Brown Jackson. Commenting on Brown Jackson's appointment, US President Joe Biden said, "Confirming Ketanzi's nomination was a historic moment for us. I have been able to take another step to reflect diversity in the United States Supreme Court. He will be an incredible judge and I am very honored to be able to share this historic moment with him. " Ketanji has served as a judge in the Federal and Appellate Division for nearly 10 years. Last February, President Joe Biden nominated him to replace 63-year-old Justice Stephen Brayer. The issue of appointing judges to the US Supreme Court was heard for four days before the Senate Judiciary Committee in February. Democrats then praised the 51-year-old Ketanji's experience and deep wisdom.
