(CNN) -- Secretary of State Hillary Clinton has canceled a scheduled trip to Britain and Turkey after her mother fell ill, a senior State Department official said Monday night.
Clinton had been scheduled to attend a conference on Afghanistan on Wednesday in Istanbul, with a stop in London for talks with her British counterpart, Foreign Secretary William Hague, on the way. No details of her mother's illness were disclosed.
Dorothy Rodham made occasional campaign appearances with her daughter during Clinton's unsuccessful Democratic presidential bid in 2008, and helped the former first lady raise money to retire her campaign debt. She also made trips with the Clintons during their years in the White House, including a 2000 visit to India and a 1998 trip to China.
