Governor Richardson backs Obama

By Matthew Bigg

PORTLAND, Oregon (Reuters) - Sen. Barack Obama won a coveted endorsement from New Mexico Gov. Bill Richardson on Friday while the State Department apologized that employees snooped into the Illinois Democrat's passport files and those of his two main White House rivals.

The backing from the Hispanic governor is a victory for Obama and could improve his chances of winning over Latino voters who have leaned toward New York Sen. Hillary Clinton.

A Clinton adviser dismissed the endorsement as not significant at this stage in the race.

Obama and Clinton are in a heated battle to represent the Democrats against the presumptive Republican nominee, Sen. John McCain of Arizona, in the November 4 presidential election to succeed President George W. Bush.

In an embarrassment to the Bush administration, the State Department on Friday revealed that the passport records of all three major candidates had been improperly viewed by three contract employees and by a regular department staffer.

Secretary of State Condoleezza Rice called Obama, Clinton and McCain to apologize and the State Department said it was conducting an investigation and would look at how to tighten its systems to prevent such privacy violations.

"It is deeply disturbing, what's happened," Obama told a news conference.

"When you have not just one but a series of attempts to tap into people's personal records, that's a problem not just for me but for our health in this country and so I expect a full and thorough investigation."
