Time magazine reminds us that President Obama had this to say about the use of military force back in 2007 when he was candidate Obama:
In 2007, Barack Obama was asked when Presidents have the authority to launch a military strike without congressional authorization. He had a precise answer at the ready.
“The President does not have power under the Constitution to unilaterally authorize a military attack in a situation that does not involve stopping an actual or imminent threat,” Obama told the Boston Globe.
Joe Biden thought such an action would warrant impeachment. I guess by Presidents, they meant only Presidents named Bush.
