Former White House correspondent Helen Thomas told a national conference of campus journalists that President Obama owes her an apology for his criticism last year of her comments about Israel. "I want an apology from the president," Thomas, 90, said Tuesday to the hundreds of student journalists and their advisers attending the keynote session of the annual spring convention of College Media Advisers (CMA) at the Marriott Marquis Hotel in New York City. Shin Inouye, director of specialty media in the presidential press office, said the White House would not comment on Thomas' demand for a presidential apology.
