Bill Richardson of New Mexico plans to endorse Sen. Barack Obama in the Democratic race for president Friday, an Obama campaign spokesperson told CNN.
Richardson plans to join Obama at a rally in Portland, Oregon, at 12:30 p.m. Friday.
In an e-mail to supporters, Richardson said Obama will be a "historic and a great president, who can bring us the change we so desperately need by bringing us together as a nation here at home and with our allies abroad."
Richardson also said in the e-mail that he was touched by Obama's recent speech on race in America, saying he "understands clearly that only by bringing people together, only by bridging our differences can we all succeed together as Americans."
Richardson is the nation's only Hispanic governor. Hispanics have tended to support Obama's rival, Sen. Hillary Clinton, in the race for the Democratic presidential nomination.
