SAN JUAN, Puerto Rico - President Barack Obama told Puerto Ricans today that he's committed to their success and self-determination as he made the first official presidential visit to the U.S. island territory in 50 years.

The quick trip also allowed Obama to court the millions of Puerto Ricans who live on the mainland and could be an important voter bloc in the 2012 presidential election.

Obama spoke to a friendly audience at the airport in San Juan shortly after arriving on Air Force One from Florida - a crucial swing state home to hundreds of thousands of Puerto Ricans.

In his remarks, the president quickly turned to the important issue of the island's status, renewing his commitment to allowing residents to determine their own future through a referendum.
