President Bush nominated White House counsel Harriet Miers to serve on the Supreme Court, filling the vacancy that will be created by Sandra Day O'Connor, who is retiring. Miers, a 60-year-old Dallas native, has never been a judge. In the past, she has been president of the Texas State Bar and the Dallas Bar Association. She would be the second woman on the Supreme Court, along with Ruth Bader Ginsburg. John Roberts, who will take his seat as the new chief justice of the U.S. later Monday, was originally selected by President Bush to replace O'Connor. However, that changed when William Rehnquist died last month from cancer, leading to Roberts being tapped to preside over the court. The Senate will have to confirm the nomination of Miers before she can join the court.
