U.S. President Donald Trump is set to attend oral arguments at the Supreme Court of the United States on the issue of birthright citizenship, marking the first time a sitting president will be physically present during proceedings.

The hearing centers on legal challenges related to birthright citizenship, a constitutional principle under the 14th Amendment, which grants automatic citizenship to most individuals born on U.S. soil.

Trump’s decision to attend highlights the importance of the case to his administration, as the issue has been central to his immigration policy agenda. Observers say the move could heighten attention on the case and its broader political implications.

Traditionally, U.S. presidents maintain distance from the judiciary to preserve the separation of powers, making this appearance an unprecedented development in modern American history.
