The penultimate day of the U.S. Supreme Court’s current term unfolded like a political novel. In a single morning, President Donald Trump secured a landmark expansion of presidential authority while simultaneously suffering three significant legal setbacks.
The Court’s rulings on Monday made one thing unmistakably clear: even a Supreme Court with a 6–3 conservative majority is not a unified bloc in Trump’s favor. On several key issues, some conservative justices joined their liberal colleagues, producing outcomes that were far from what the president had hoped.
Nearly a century ago, the Supreme Court unanimously ruled that President Franklin D. Roosevelt could not dismiss commissioners of independent regulatory agencies at will because Congress had deliberately insulated those agencies from direct presidential control. On Monday, the Court overturned that longstanding precedent.
Writing for the majority, Chief Justice John Roberts argued that officials responsible for carrying out presidential policies must remain accountable to the president, who is ultimately accountable to the American people. Six conservative justices—including three appointed by Trump himself—supported the decision, while the Court’s three liberal
justices dissented.
The implications extend far beyond a single agency. The ruling strengthens presidential authority over a broad range of independent federal bodies, including agencies responsible for consumer protection, communications, labor relations, financial regulation, and environmental oversight.
Trump celebrated the decision on Truth Social, writing: *”A 90-year precedent has been completely overturned. At the very moment it was needed most, presidential power has been greatly expanded!”*
Yet on the very same day, the Court dealt Trump an important defeat.
In a 5–4 ruling, the justices blocked his effort to remove Federal Reserve Governor Lisa Cook. Chief Justice Roberts and Justice Brett Kavanaugh joined the Court’s three liberal justices in preserving Cook’s position.
Trump had accused Cook of mortgage fraud, but the broader dispute stemmed from his long-running frustration with the Federal Reserve’s refusal to reduce interest rates. Writing for the majority, Roberts emphasized that Cook deserved an opportunity to respond to the
allegations against her and warned that allowing presidents to remove Federal Reserve officials for political reasons could threaten the central bank’s independence and undermine financial stability.
Trump also lost another major case involving mail-in voting.
The Court upheld the legality of counting mail ballots that are postmarked by Election Day but arrive afterward, rejecting Trump’s challenge. Justice Amy Coney Barrett, another Trump appointee, authored the majority opinion, joined by Chief Justice Roberts and the Court’s three liberal justices.
Barrett wrote that the Constitution grants states broad authority to regulate the time, place, and manner of conducting elections. She rejected Trump’s repeated claims that mail-in voting is inherently vulnerable to widespread fraud, concluding that any policy changes
should be addressed through the democratic process rather than judicial intervention.
Following the ruling, Trump renewed his call for Congress to pass his election reform package, which would significantly restrict mail-in voting. Although the Republican-controlled House has approved the legislation, it remains stalled in the Senate, where Democrats and several Republicans have prevented it from advancing.
Monday’s 28-page order list also included another setback for the president.
Without explanation, the Supreme Court declined to review *Trump v. Carroll*, leaving intact the $5 million civil judgment against Trump. A jury found in 2023 that Trump had defamed former magazine columnist E. Jean Carroll after she publicly accused him of sexually assaulting her in a New York department store dressing room during the 1990s.
Reacting on Truth Social, Trump denounced the decision, writing, *”I will continue fighting this weaponization and lawfare with every ounce of my strength. This injustice cannot stand.”*
Although Trump is continuing his appeal of a separate $83.3 million defamation judgment in another Carroll case, the Court’s refusal to hear this appeal effectively ends his effort to overturn the earlier $5 million verdict.
Taken together, Monday’s four decisions send a nuanced message about the current Supreme Court.
The justices appear willing to expand presidential authority over the executive branch and the federal bureaucracy. At the same time, they remain prepared to draw institutional boundaries when disputes involve the independence of the Federal Reserve, the integrity of the electoral process, or certain personal legal matters involving the president.
American politics has long operated on dramatic shifts in executive priorities—from Barack Obama to Donald Trump, from Joe Biden back to Trump. Monday’s decisions are likely to intensify those swings by giving future presidents greater authority to replace leaders of independent agencies.
Yet the rulings also demonstrate that the Court continues to preserve certain constitutional guardrails. Even within its conservative majority, there is no guarantee of ideological unanimity when questions arise about institutional independence or democratic governance.
As the nation’s highest authority on constitutional interpretation, the Supreme Court delivered a powerful reminder on Monday: Donald Trump left the courtroom with both one of his biggest victories and several of his most consequential defeats—on the very same day.
