McCain mid-sentence

ATLANTA, Georgia (CNN ) – Politicians are all too used to reporters’ cell phones interrupting their news conferences. But this time, it was the candidate’s own violation.

Senator John McCain, R-Arizona, was speaking to reporters in Sacramento, California Monday, and was in the middle of an answer on fund-raising when the telltale ring came from his jacket pocket.

The GOP presidential hopeful looked at the number and said, “that’s not my wife, so I won’t answer it.” He then tucked it back in his pocket, and resumed, saying “let me start over. We’re doing better in fund-raising this quarter.”

No word on who dialed the candidate in the middle of his news conference. But we know it wasn’t the White House - McCain wasn’t on the list of three senators that President Bush called Monday from Air Force One.
