Lawmakers on both sides of the aisle say President Obama's use of deadly drones against Americans involved with al Qaeda needs closer inspection.
Former Arkansas Gov. Mike Huckabee told CBN News the question that needs to be asked is if the Constitution allows the president to have sole power to decide to take the life on an American.
"The question is can that ever be constitutional?" Huckabee said. "Because if it can and the individual president makes the decision as to what the criteria is, that's a pretty dangerous precedent. It's why we have three branches of government; it's for the checks, the balances, the oversights," he continued.
"When you remove the oversight and you remove the check and balance, then you have one branch of government that becomes judge, jury, and executioner," Huckabee said. "You bypass the judicial and the legislative branches. We are really operating in some very, very strange territory there."
Some lawmakers are proposing the formation of a special court to review the use of drone strikes.
"I think that the rules and the practices that the Obama administration has followed are quite stringent and are not being abused. But who is to say about a future president?" former Secretary of Defense Robert Gates said.
Gates, who led the Pentagon for Presidents George W. Bush and President Obama and previously served as the Central Intelligence Agency's director, said Obama's use of the unmanned drones follows tight rules. But he said he shared lawmakers' wariness about the program.
