The Twitter hashtag #LetLizSpeak was trending on social media Wednesday. And over 6 million people saw a video from Elizabeth Warren, a member of the United States Senate. She posted her video on Facebook Tuesday night. Warren is a member of the Democratic Party from Massachusetts. And Liz is a nickname for Elizabeth. On Tuesday, the Senate was considering whether to approve Senator Jeff Sessions, a Republican, as the next U.S. Attorney General. Sessions is President Donald Trump’s choice for the position. The attorney general is a member of the president’s cabinet and heads the Department of Justice. During the Senate debate on Sessions’ nomination, Warren read a letter written by Coretta Scott King. King was the wife of civil rights leader Martin Luther King [Junior]. She wrote the letter in 1986, when Sessions, then a lawyer for the federal government, was being considered for a federal court judgeship. Tuesday night, Warren was reading Coretta Scott King’s letter aloud on the Senate floor. King wrote that Sessions used his power in Alabama to “chill the free exercise of the vote by black citizens...” That is when Senator Steve Daines, a Republican from Montana, intervened. He warned Warren that Senate rules bar one senator from speaking badly about another. Warren was permitted to continue reading the letter. But she was stopped again, this time by Republican Senate Majority Leader Mitch McConnell of Kentucky. Warren was told she could not continue reading the letter. She said, “I am surprised that the words of Coretta Scott King are not suitable for debate in the United States Senate.” Warren asked to continue speaking, but her appeal was rejected. A majority of senators voted to bar her from speaking about Sessions until after his confirmation hearing on Wednesday. Warren left the Senate floor, went to a nearby room and continued reading the letter. She posted the video to her Facebook page. By Wednesday afternoon, the 15-minute video received over 400,000 comments.
