Republican Presidential candidate Donald Trump called President Barack Obama "perhaps the worst president in the history of the United States," and Obama had something to say about it.

The President's response was in a skit on "Jimmy Kimmel Live!" He read a tweet from Trump and then said at least he will go down as a president, period.

President Obama will go down as perhaps the worst president in the history of the United States!
