Direct quote from the article.
"I am confident the Supreme Court will not take what would be an unprecedented, extraordinary step of overturning a law that was passed by a strong majority of a democratically-elected congress," President Obama said at a White House event in the Rose Garden today.
Webster : Unprecedented - adj. having no precedent or parallel; unheard-of; novel.
Fact - The Supreme Court has overturned over 1,000 laws including federal, state, and city .
Just another example that he can do and say whatever he wants to.
