AP:Republican campaign dropout Mitt Romney endorsed John McCain for the party's presidential nomination and asked his national convention delegates to swing behind the likely nominee.
"Even when the contest was close and our disagreements were debated, the caliber of the man was apparent," the former Massachusetts governor said, standing alongside his one-time rival at his now- defunct campaign's headquarters. "This is a man capable of leading our country at a dangerous hour."
"Primaries are tough," said McCain, referring to their earlier rancor. "We know it was a hard campaign and now we move forward, we move forward together for the good of our party and the nation."
The two met privately before appearing together at a news conference. McCain had campaigned in Vermont and Rhode Island but added a flight to Boston to accept the endorsement.
