Trump's Inauguration Speech	English	朝日新聞, 2017年1月22日, 朝刊

Chief Justice Roberts, President Carter, President Clinton, President Bush, President Obama, fellow Americans, and people of the world: thank you.
We, the citizens of America, are now joined in a great national effort to rebuild our country and restore its promise for all of our people.
Together, we will determine the course of America and the world for many, many years to come.
We will face challenges. We will confront hardships. But we will get the job done.
