(CNN) - Republican presidential candidate Michele Bachmann said President Obama would be a "dictator" if he raised the debt ceiling by executive order, using the 14th amendment of the U.S. Constitution as justification.

"It's Congress that does the spending. The president is prohibited to do that. If he had the power to do that he would effectively be a dictator," the Minnesota Congresswoman said Thursday on CNN's "American Morning." "There would be no reason for Congress to even come to Washington, D.C. He would be making the spending decisions … Clearly that's unconstitutional."
