Presidential candidate Ron Paul said it is "possible" to impeach President Obama for killing American citizen and al-Qaeda operative Anwar al-Awlaki.
Paul has been outspoken against the action in Yemen that took out al-Awlaki last Friday. He insists it is against the Constitution to punish an American citizen without giving him or her due process of the law.
Speaking in New Hampshire on Monday, Paul went a step further, saying impeachment is possible. But then again, he added, he likely could have impeached every president for something they did while in office.
