Donald Trump's first 100 days as U.S. president (January 20–April 29, 2017) were marked by aggressive executive actions and a focus on his "America First" agenda. Key highlights include:
**Immigration:** Trump signed an executive order banning travel from seven Muslim-majority nations (later blocked by courts), intensified border security, and pushed for a U.S.-Mexico border wall, though Congress resisted funding it.
**Economy:** He withdrew from the Trans-Pacific Partnership (TPP), initiated NAFTA renegotiations (later USMCA), and announced plans for tax reforms, culminating in the 2017 Tax Cuts and Jobs Act.
**Deregulation:** Trump prioritized rolling back environmental and financial regulations, approving the Keystone XL and Dakota Access pipelines, and dismantling Obama-era climate policies like the Clean Power Plan.
**Healthcare:** A failed attempt to repeal the Affordable Care Act (ACA) highlighted early legislative struggles, though executive orders weakened ACA enforcement.
**Supreme Court:** Neil Gorsuch was confirmed, shifting the court conservatively.
**Foreign Policy:** He ordered missile strikes in Syria after chemical attacks and adopted a confrontational stance toward North Korea.
**Controversies:** Protests, including the Women's March, and ongoing Russia investigation overshadowed his agenda. While Trump touted job growth and stock market gains, critics cited polarization and policy setbacks. His tenure began with bold promises but faced legal and political hurdles.
