The first 100 days are a presidential milestone and a benchmark that dates back almost a century. The 100-day marker began with Franklin D. Roosevelt in 1933 when he hit the ground running during the Great Depression and called for a special session.

Trump used his time on stage to luxuriate in the crowd's adoration, blame Joe Biden for various national problems, and insist that he, as president, is not getting the credit he deserves.

Trump has signed more than 140 executive orders since inauguration, the most of any U.S. president in 100 days. As a whole, Americans are torn over his aggressive policy moves. Only about 4 in 10 approve of how Trump is handling the presidency, according to the Associated Press. His ratings on the economy and trade are lower than that.
