Julian Zelizer wrote for CNN about Trump’s first 100 days in office:
The clock is ticking. President Trump has between now and April 29 to make the most of his Hundred Days.
Ever since Franklin Roosevelt introduced the term in 1933 as he pushed through Congress one of the boldest domestic agendas that the nation had seen, 75 bills in total, these important weeks in the early history of a presidency have become a lens through which politicians and pundits view the effectiveness of a new leader.
The Hundred Day record for presidents is mixed.
