In an unprecedented move, U.S. President Donald Trump attended a Supreme Court hearing on Wednesday regarding his executive order aimed at limiting birthright citizenship. This directive seeks to prevent automatic citizenship for children born in the U.S. to parents who are not citizens or permanent residents. During the more than two-hour session, several justices appeared skeptical of the administration's position, particularly in light of a lower court ruling that blocked the policy. The case, titled Trump vs Barbara, is set to receive a verdict by the end of June. Outside the courthouse, demonstrators gathered to voice their opposition to Trump, with heightened security present. Trump's relationship with the judiciary has been tense, as he has criticized justices, including his own appointees, following rulings against him. Notably, Trump is the first sitting president to attend a Supreme Court oral argument, a significant moment in U.S. history.
