WASHINGTON — U.S. Sen. Sam Brownback said he has reservations about Sonia Sotomayor, President Obama’s nominee for the Supreme Court. “While I celebrate Sonia Sotomayor’s life story, I am troubled by some of her statements,” he said. “Mow that the president has nominated her … she deserves a fair and respectful hearing. I look forward to a thorough process and to hearing more from her. I do have serious questions about her record and her judicial philosophy regarding how she views the role of the court. In my view, the role of a justice is as an umpire, not a policy maker.”
