The administration undertook several significant policy actions and diplomatic efforts in early December 2025 across domestic and international fronts. On the economic side, President Trump announced the reset of the Corporate Average Fuel Economy (CAFE) standards, reversing what were described as costly and unlawful targets from the prior administration, an action projected to save American families billions and prevent car price increases. This period also saw a major financial milestone for the "Trump Accounts," a new savings tool for children established under the Working Families Tax Cuts Act, which received a landmark $6.25 billion charitable commitment from Michael and Susan Dell. In health policy, the President directed the Secretary of Health and Human Services and the CDC Director to review U.S. core childhood vaccine recommendations, noting that the United States recommends significantly more vaccinations than its developed peer countries, and mandated an update to align with scientifically superior international best practices if warranted. Regarding sovereignty and foreign relations, the Monroe Doctrine was reaffirmed and expanded through a "Trump Corollary," asserting that the American people control their own destiny without interference from foreign nations or globalist institutions, supported by border security measures, the dismantling of narco-terrorist networks, and new trade deals in the Western Hemisphere. Domestically, the White House launched a Media Bias Portal to allow Americans to submit tips regarding false or biased articles, and highlighted law enforcement successes like Operation Metro Surge in Minneapolis targeting criminal illegal immigrants. Finally, First Lady Melania Trump announced the White House Christmas theme, "Home Is Where The Heart Is," and commended the diplomatic progress made in the Russia-Ukraine Children’s Reunification Initiative.
