Trump kicks off morning with new furious attack on Supreme Court

President Donald Trump started his Thursday morning with a brief but furious attack on the Supreme Court on his Truth Social platform.

"Kangaroo Court!!!" wrote Trump.

This comes after a disastrous day of oral argument for Trump's executive order limiting birthright citizenship to only the children of citizens or lawful permanent residents — an extreme and unprecedented change not only unauthorized by Congress but explicitly contradicting the definition of citizenship laid out in the 14th Amendment, and over a century of precedent from federal courts establishing all persons born in the United States have citizenship.

If the order is allowed to go into effect, potentially millions of people born in the United States to undocumented immigrants, or even to legal residents who don't have permanent status, would be ineligible for federal documents like passports that affirm citizenship.

The administration was raked over the coals by a majority of the justices, including conservatives like Chief Justice John Roberts and Trump's own appointee, Justice Neil Gorsuch.

The president personally attended oral argument, the first time this has ever been done by a president in U.S. history. But he stormed out early after it became clear the case wasn't going in his favor.
