Diane Rehm and John Hagedorn were married at the Washington National Cathedral. In 1998, Rehm began having difficulty speaking normally. Eventually, she was treated at Johns Hopkins Hospital and was diagnosed with spasmodic dysphonia, a neurological condition that affects the quality of her voice. The condition is treatable but not curable. After a short break, Rehm's career continued and her radio show went on until December 2016. Career Rehm began her radio career in 1973 as a volunteer for WAMU's The Home Show. In 1979, she took over as the host of WAMU's morning talk show, Kaleidoscope, which was renamed The Diane Rehm Show in 1984. Rehm has interviewed many political and cultural figures, including John McCain, Barack Obama, Madeleine Albright. She has said that her most touching interview was with Fred Rogers of the PBS program Mister Rogers' Neighborhood, conducted just before his death. Rehm has described her interviews with Bill Clinton and Hillary Clinton to have been "amazing experiences." She has written three autobiographical books. The first, Finding My Voice, dealt with her traditional upbringing in a Christian Arab household, her brief first marriage and divorce, her 50-year marriage to John Rehm, raising her children, the first 20 years of her radio career, and her battles with depression, and spasmodic dysphonia. Together with John Rehm she co-wrote Toward Commitment: A Dialogue About Marriage, which was published in 2002. Her memoir, On My Own, was published by Alfred A. Knopf in 2016. The final broadcast of The Diane Rehm Show was aired on December 23, 2016. Corporation for Public Broadcasting report In 2005, a private study funded by the Corporation for Public Broadcasting reported that Rehm booked 22 liberal guests for every 5 conservative guests. The study was criticized as a politicized attempt to, in Rehm's word, "scare" journalists with the accusation of liberal bias. One criticism of the study concerned its criteria of what constituted "liberal" – a category which included seemingly moderate Republicans such as Senator Chuck Hagel and former Representative Bob Barr. The study was commissioned by Kenneth Tomlinson, whose appointment to the chairmanship of the CPB by George W. Bush had been criticized by liberals as politically motivated. Tomlinson hired Indiana consultant Frederick W. Mann, a conservative thinker previously associated with the Young America's Foundation, which has described itself as "the principal outreach organization of the Conservative Movement".
