To answer Ted's question, Mitch McConnell wouldn't try to stymie her speech if she did.
While Senator Warren continued reading the letter, Senate Majority Leader Mitch McConnell of Kentucky interrupted, saying, "The senator has impugned the motives and conduct of our colleague from Alabama, as warned by the chair." Senator McConnell objected to a line from Ms. King's letter, "Mr. Sessions has used the awesome power of his office to chill the free exercise of the vote by black citizens", which Senator Warren had quoted prior to the warning. ... Senator Jeff Merkley of Oregon subsequently read the letter from Coretta Scott King without objection.
