U.S. President Barack Obama has arrived in Spain for an 18-hour stop, the first U.S. president to visit in 15 years. 
He plans meetings in Madrid with Spanish leaders and a visit with King Don Felipe IV. He'll also travel to the U.S. Naval Station Rota to address troops. 
The White House says the visit will highlight security cooperation between the two nations and a strong political and economic relationship. 
Obama, who is traveling to Spain from the NATO summit in Warsaw, Poland, cut a day off his visit after the shooting death of five police officers in Dallas and he will come back to the U.S. on Sunday instead of Monday as had been planned.
