• Supreme Court Allows Challenge to California's Emission Limits — The U.S. Supreme Court ruled in favor of fossil fuel companies and 17 Republican-led states, allowing them to challenge California's waiver to set stricter car emission standards than federal limits. The 7-2 decision overturns a lower court ruling that dismissed the lawsuit due to lack of standing. This waiver, periodically granted since 1967, has enabled California to lead in reducing vehicle pollution. The ruling does not immediately end California's standards but opens the door for legal challenges against them.

The legal action has been met with condemnation from officials in the targeted states.

• Trump signed executive order stopping enforcement of state climate laws — On April 8, 2025, Trump signed an executive order instructing the Department of Justice to "stop the enforcement" of state climate laws, which his administration suggested are unconstitutional or unenforceable. The order states "These State laws and policies are fundamentally irreconcilable with my Administration's objective to unleash American energy. They should not stand." The action represents Trump's attempt to preempt state climate initiatives.
• Trump administration freezes $790 million in federal funding to Northwestern University — The Trump administration froze $790 million in federal funding to Northwestern University as part of broader crackdowns on students and faculty members across US colleges who have expressed opposition to Israel's military operations in Gaza. The freeze targeted the university in response to activism and legal representation related to pro-Palestinian causes.
• White House freezes federal funding for Cornell and Northwestern universities — The Trump administration froze over $1 billion in federal funding for Cornell University and $790 million for Northwestern University, citing investigations into alleged "failure to protect Jewish students" following pro-Palestinian campus protests. The freeze includes grants and contracts from federal departments of health, education, agriculture, and defense. Cornell received over 75 stop-work orders from the Department of Defense affecting research in defense, cybersecurity, health, and cancer. The action follows warning letters sent to 60 universities in early March and comes after Cornell's president published a defiant op-ed defending academic freedom and free discourse.
• Princeton University reports suspension of federal research grants — Princeton University announced that dozens of its federal research grants were suspended over allegations that the university promoted antisemitism.

• Trump administration considers consent decree to place Columbia University under federal control — The Trump administration is reportedly considering placing Columbia University under a legally binding consent decree, a dramatic escalation following the university's acceptance of administration-demanded changes as a condition for restoring $400 million in suspended federal grants and contracts. The proposal originates from the administration's antisemitism taskforce, composed partly of Justice Department lawyers who question Columbia's good faith compliance. If Columbia resists, the Justice Department would need to present its case in court, risking prolonged litigation and continued funding withholding.
• Trump administration freezes nearly $1 billion in federal funding from Cornell University — During a cabinet meeting, President Trump pressed Education Secretary Linda McMahon on withholding federal funds from universities deemed "not behaving."

Harvard's legal team, citing First Amendment violations and constitutional limits on executive authority, rejected the demands as governmental overreach into academic freedom. Within hours, the administration froze $2.2bn in grants and a $60m contract in retaliation.
• Trump administration withheld Harvard University federal funding pending government control of admissions and intellectual content — On April 11, the Trump administration announced it would withhold $2.2 billion in grants already awarded and a $60 million contract from Harvard University unless the university permitted the federal government to control its admissions and intellectual content. The administration framed the action as addressing antisemitism. On April 22, Harvard filed suit against the departments of Health and Human Services, Justice, Education, Energy, and Defense, the General Services Administration, the National Institutes of Health, National Science Foundation, NASA, and their leaders, alleging violation of the First Amendment and abuse of legal authority.
• White House claims letter to Harvard withholding federal funds was "unauthorized" — On Friday, April 18, the administration claimed that a letter sent to Harvard University on April 11 withholding federal grants until the university granted administration officials power over the school's students and programs was "unauthorized." However, the White House simultaneously stated it was standing by the letter. The letter was signed by three federal officials, placed on official letterhead, and sent from the email of a senior federal official. Harvard responded by pointing out the letter's official provenance and noting that the government's actions had "real-life consequences."
• Harvard University rejected Trump administration demand for control over university governance — On April 11, 2025, Harvard University rejected the Trump administration's demand to regulate "intellectual and civil rights conditions" at Harvard, including its governance, admissions, programs, and extracurricular activities, in exchange for continuation of $2.2 billion in multiyear grants and a $60 million contract. Harvard's lawyers stated the university would not surrender its independence or relinquish constitutional rights and would not allow itself to be taken over by the federal government.
