Barack Obama's Drone Strike That Killed an American Citizen

Do you think Barack Obama ordering a drone strike that killed an American citizen warrants an investigation of that? Um, they might have already been an investigation. I don't know what the vetting process inside of orders from the government. There probably always should be when, when there's collateral damage. Didn't it happen in Afghanistan or Pakistan? Wasn't there a hospital that we accidentally bombed? Like a year and a half ago, he thinks probably like 20 or 30 people died and it was all civilians.
