Donald Trump continued his feud with Sen. John McCain (R-Ariz.) Saturday when he criticized the military record of the onetime prisoner of war.

"He's a war hero because he was captured," Trump said during an appearance at the Family Leadership Summit in Ames, Iowa, on Saturday. "I like people who weren't captured."

"Perhaps he's a war hero, but right now he's said some very bad things about a lot of people."

McCain spent five and a half years in a North Vietnam prison where he was tortured after his Skyhawk dive bomber was shot down in 1967 . President Barack Obama , who defeated McCain in the 2008 presidential race, has praised the Arizona senator as a "genuine war hero ."
