It was one of the most consequential days at the United States Supreme Court in recent memory.
On the final day of its term, the Court's conservative 6-3 majority delivered a string of blockbuster rulings that reshaped the legal landscape on some of the nation's most hotly debated political issues.
From transgender athletes in women's sports to campaign finance, the decisions marked major victories for conservatives and President Donald Trump while dealing significant setbacks to Democrats and progressive activists.
The biggest headline came in the battle over transgender athletes competing in girls' and women's sports.
In a 6-3 decision written by Justice Brett Kavanaugh, the Court upheld laws in Idaho and West Virginia restricting girls' and women's school sports to biological females. The majority concluded that the laws do not violate either the Equal Protection Clause or Title IX, effectively validating similar laws already enacted in more than two dozen Republican-led states. Kavanaugh wrote that states may preserve female athletic competition based on biological sex while acknowledging that transgender students deserve dignity and respect.
For years, Republicans argued the issue was never about politics, it was about fairness. They maintained that biological males possess physical advantages that undermine opportunities created for female athletes under Title IX.
Trump wasted no time celebrating.
Calling the ruling "A BIG WIN," the president praised the Court's decision, while the White House amplified the message across social media with the declaration: "NO MEN IN WOMEN'S SPORTS." The decision instantly became one of the defining legal victories of Trump's second term and a cornerstone issue heading into the 2026 midterm elections.
The Court followed with another enormous win for Republicans.
In another 6-3 ruling, the justices struck down decades-old federal limits on how much money national political parties may spend in coordination with their own candidates. The challenge was brought by Vice President JD Vance and Republican committees, who argued the restrictions violated the First Amendment. Justice Kavanaugh again wrote for the majority, concluding that the spending limits unconstitutionally restricted political speech.
Trump again declared victory, calling the decision "A BIG WIN FOR REPUBLICANS" as both parties prepare for the 2026 elections.
The ruling continues a decades-long trend by the Court of treating political spending as constitutionally protected speech, a philosophy that has steadily reshaped campaign finance law since Citizens United.
The day was not a complete sweep for Trump, however.
In perhaps the most legally significant immigration case of the term, the Court rejected the administration's effort to narrow birthright citizenship under the Fourteenth Amendment. In a separate 6-3 ruling, the justices held that children born in the United States to parents who are unlawfully or temporarily present remain American citizens at birth, reaffirming a longstanding interpretation of the Constitution. Chief Justice John Roberts wrote for the majority, joined by the Court's three liberal justices and Justice Amy Coney Barrett.
Even with that setback, Tuesday represented another unmistakable sign of how dramatically the Supreme Court has changed since Trump appointed Justices Neil Gorsuch, Brett Kavanaugh and Amy Coney Barrett during his first term.
On issue after issue, including administrative power, religious liberty, gun rights, campaign finance and now transgender athletics, the Court has increasingly embraced constitutional originalism while giving greater deference to state governments and limiting federal authority.
For Republicans, it reinforced key pillars of their platform just months before critical midterm elections. And for President Trump, the Court he helped reshape once again demonstrated why judicial appointments may prove to be one of the most enduring legacies of his presidency.
