Donald Trump’s first 100 days as U.S. President were marked by bold promises, rapid executive actions, and deep political polarization. He moved swiftly on immigration, withdrawing from the Trans-Pacific Partnership and issuing controversial travel bans. Despite pledges, Obamacare repeal stalled in Congress. His administration emphasized “America First” policies, triggering global reactions. The period showcased Trump’s unorthodox leadership style, reliance on Twitter, and a combative relationship with the media. While supporters praised his disruption of the status quo, critics raised concerns about inexperience and division. His early presidency set the tone for a chaotic, unpredictable term.
