Example Input: (CNN) -- The Washington Post's Chris Cillizza recently gave President Barack Obama his "Worst Year in Washington" award.

Example Input: (CNN) In the end, Donald Trump stayed true to himself. Beset by appeals from foreign leaders and corporate titans to put the planet first, he pulled out of the Paris climate accord Thursday.
