A retired federal judge on his life on the bench and the current Supreme Court

Judge David Tatel sat on the bench of the powerful D.C. Circuit Court of Appeals for nearly three decades. Appointed by Bill Clinton, he became a prominent, liberal-leaning voice in the judiciary, widely considered a top candidate for the Supreme Court had Al Gore won the 2000 election. Tatel was known as a brilliant legal mind, whose opinions helped shape laws affecting voting rights, the environment, internet regulations and press freedoms. But he was also known for another reason: he was blind.David Tatel retired from the bench in January. He joins Diane to discuss his new book, "Vision: A Memoir of Blindness and Justice." In it, he opens up about his experience as a blind judge – and his grave concerns about the Supreme Court.
