The State Department says the passport files of all three presidential candidates have been breached.

Spokesman Sean McCormack says the breaches of John McCain and Hillary Rodham Clinton's files were not discovered until the privacy breach involving Barack Obama's records triggered a search.

The Obama breach was detected by internal computer checks. The State Department says certain records, including those of high-profile people, are electronically flagged to tip off supervisors if somebody tries to view the records without authorization.

McCormack says the same contract employee who was reprimanded for taking an unauthorized look at Obama's file also accessed McCain's. Two other contract workers have been fired over the Obama incident.

Secretary of State Condoleezza Rice spoke with Obama and Clinton to apologize.

McCain is in Paris. He says any breach of privacy deserves an apology and a "full investigation." The State Department's inspector general is conducting one.
