The Trump administration has executed what experts call the most sweeping environmental policy reversal in U.S. history. President Trump officially revoked the 2009 "endangerment finding," the scientific pillar that allowed the EPA to regulate greenhouse gases as a threat to public health. Simultaneously, he announced the end of federal vehicle emission standards for models through 2027. Trump dismissed climate change as a "scam," claiming these moves would save taxpayers over $1.3 trillion and lower car prices.

On the trade front, the White House finalized a reciprocal trade deal with Taiwan, setting a 15% tariff on Taiwanese imports while Taiwan agrees to eliminate tariffs on nearly all American goods. Domestically, following nationwide protests, the administration also announced the end of a controversial immigration-enforcement surge in Minnesota. These moves underscore a "U.S.-first" strategy that is reshaping both global trade and international climate cooperation.
