In his first 100 days, President Donald Trump exerted his power in a sweep and scale that has no easy historical comparison.

His actions target the architecture of the , the , and the Reagan Republican orthodoxy of free trade and strong international alliances. He has taken direct aim at law, media, public health and culture, attempting to bring all to heel.

Here are some key takeaways from the most consequential start of a term of an American presidency since Franklin D. Roosevelt.

Trump has tried to bend the U.S. economy to his will. But one force is unbowed: .

The president says his tariffs will eventually be “beautiful.†So far, it’s been an difficult three months with consumer confidence plummeting, stock markets convulsing and investors losing confidence in the credibility of Trump’s policies.

He has imposed hundreds of billions of dollars in tariffs, including on America’s two largest trading partners, . Chinese goods are getting taxed at a combined 145%.

He has rewarded the coal and oil sectors by attacking alternative energy, yet his tariffs pushed up the price of the steel and other materials that the energy industry needs to build out production.

DOGE

Trump promised to take on what he called in government. He tapped Elon Musk to lead the effort.

Musk turned his plan for a into one of the most polarizing and consequential pieces of Trump’s first 100 days.

The billionaire entrepreneur approached the task with a tech mogul ethos: break things, then see what you want to fix. Firings were widespread and indiscriminate. Programs were eliminated with limited analysis.

It is . His plans for slashing $1 trillion out of the budget were pared back to $150 billion.

Immigration

Cracking down on illegal immigration was the anthem of Trump’s campaign, and it is the issue where he has the greatest support.

He has followed through by implementing some of the in the nation’s history, even as the have yet to materialize.

Trump invoked the to deport immigrants with limited due process, then used it to send hundreds of alleged Venezuelan gang members to a mega-prison in El Salvador in defiance of a court order.

The administration pledged to end for people who were born in the U.S., while proposing “gold cards†that would allow foreigners to buy American citizenship for $5 million.

He went after former officials who criticized him or correctly asserted that he had lost the 2020 presidential election to Democrat Joe Biden. And he targeted elite universities whose policies irked him.

Diplomacy and international relations

Trump has rejected the post-World War II order that has formed the basis for global stability and security.

He has rejected long-standing alliances and hinted at scaling back the U.S. . Longtime allies such as Germany and France have suggested they no longer can depend on Washington.

Trump also pledged a swift and Gaza, so far to little effect.

His actions have led allies in Europe, along with Canada, Japan and South Korea, to question their reliance on the U.S.

The president has upended other multilateral organizations. And he has , long seen as an example of an effective tool to provide humanitarian aid.

At the same time, he has repeatedly , which is a Danish territory, to retake control of the Panama Canal and to make Canada the 51st U.S. state.

Congress

Congress is proving to be almost no match for .

But Trump has shown he does not necessarily want or need Congress to accomplish his goals.

The president has issued almost 10 times as many as the , bypassing Congress. DOGE is , and , that by law receive funding under the purview of Congress.

Energy and environment

Trump has reversed Biden’s focus on slowing climate change to pursue what the Republican calls U.S. “energy dominance†in the global market.

He created a and directed it to move quickly to drive up already record-high U.S. energy production, particularly fossil fuels such as oil and natural gas, and remove regulatory barriers.

Arts and culture

Dana Gioia, a poet and former chair of the , liked to say that a key to maintaining support for the NEA and other federal organizations was ensuring they backed projects in as many congressional districts as possible.

It was a bipartisan formula that lasted for some 60 years, through Democratic and Republican administrations, until Trump’s second term.

Trump has ousted leaders, placed staff on administrative leave and cut off hundreds of millions of dollars in funding that artists, libraries, museums, theaters and others in the cultural community had long counted on. Acting without congressional authorization, he has declared that institutions ranging from the to the ºÚÁϳԹÏÍø Endowment for the Humanities have become fronts for a “woke†agenda that threatens to undermine what he calls “our Vision for a Golden Age in Arts and Culture.â€

Media

Many journalists figured a second Trump term would be a challenge for their industry. Few recognized how much.

The new administration has aggressively, even innovatively, against the press since taking office. It has fought against CBS News and The Associated Press in court, the government-run Voice of America and sent the Federal Communications Commission after perceived media rivals.

“The Trump administration is on a campaign to do everything it can to diminish and obstruct journalism in the United States,†said Bill Grueskin, a Columbia University journalism professor.

The future of Voice of America, Radio Free Europe/Radio Liberty and similar services that for generations have delivered unbiased news to countries where it is in short supply is being .
