The Latest: Supreme Court is set to rule on Trump’s challenge to birthright citizenship

The Supreme Court on Tuesday will rule on the constitutionality of President Donald Trump’s order on are not American citizens.

The decision comes on the final day of a Supreme Court term that has centered on Trump’s expansive claims of presidential power — and largely ruled in his favor.

The court on Monday handed Trump a major win by upholding his firings of independent federal agency heads at will, with the exception of Federal Reserve governor Lisa Cook, who will retain her job while she fights the president’s effort to fire her over allegations of mortgage fraud.

Here’s the latest:

Monday’s ruling on federal agencies dramatically expanded presidential power

Other than at the Federal Reserve, with its role of setting interest rates, the court held that presidents have free rein to fire agency heads at will, despite federal laws that require a cause for such dismissals and a 91-year-old decision that had limited executive authority.

The justices allowed Fed governor Lisa Cook to stay in her job while she fights Trump’s effort to fire her over allegations of mortgage fraud, which she has denied.

With the six conservative justices in the majority, the nine-member court jettisoned its unanimous decision in Humphrey’s Executor that had limited when presidents can fire agencies’ board members — in part to try to ensure decision-making free of political influence.

“We hold that such protection from removal is contrary to the separation of powers enshrined in the Constitution,” Chief Justice John Roberts wrote for the court.

The court will also rule on trans athletes and campaign finances

In separate cases, the court will also decide:

Whether states can prohibit transgender athletes from playing on girls’ and women’s public school and college teams.

Whether to uphold a federal law more than 50 years old limiting how much political parties can spend in coordination with candidates for Congress and the president.

The court seemed poised to reject Trump’s birthright citizenship limits during arguments in April

Oral arguments for the case lasted more than two hours in a crowded courtroom that included Trump, the first sitting president to attend arguments at the nation’s highest court, and, in seats reserved for the justices’ guests, actor Robert De Niro.

Trump heard his administration’s top Supreme Court lawyer, Solicitor General D. John Sauer, face one skeptical question after another. Justices asked about the legal basis for the order and voiced more practical concerns.

“Is this happening in the delivery room?” Justice Ketanji Brown Jackson asked, drilling down into the logistics of how the government would actually figure out who is entitled to citizenship and who is not.

Chief Justice John Roberts suggested that Sauer was relying on quirky exceptions to citizenship to make a broad argument about people who are in the country illegally. “I’m not quite sure how you can get to that big group from such tiny and sort of idiosyncratic examples,” Roberts said.

Justice Clarence Thomas sounded the most likely among the nine justices to side with Trump.
