Two Republican presidential hopefuls are divided over President Barack Obama's plan to bring home troops from Afghanistan.
Former Utah Gov. Jon Huntsman says "this country has given its all" and the U.S. is ready to bring home troops from Afghanistan.
Former Pennsylvania Sen. Rick Santorum says that military leaders have been tied down by Obama's withdrawal strategy. He says "we should be fighting wars to win, not fighting wars for politics."
Obama has outlined plans to withdraw more than 20,000 U.S. troops from Afghanistan by the end of next summer.
