Republican presidential candidate Sen. Rand Paul, who has advocated for a more robust U.S. drone policy, defended Monday the U.S. drone strike that accidentally killed two hostages in Pakistan last week. "I tend to not want to blame the president for the loss of life here. I think he was trying to do the right thing," Paul said in a Fox News interview. The presidential hopeful's comments came days after President Barack Obama apologized to families of the two aid workers killed in the strike while they were being held by al Qaeda, Giovanni Lo Porto of Italy and Warren Weinstein of Rockville, Maryland. Paul has been scrutinized by Republicans who say his non-interventionist foreign policy would weaken the U.S. military.
