President Donald Trump made a historic visit to the US Supreme Court on Wednesday to attend arguments over the legality of a policy he considers crucial to his hardline approach toward immigration — a directive he signed last year on his first day back in office that would limit birthright citizenship.The SC justices signaled skepticism toward the legality of his directive to restrict the citizenship. Trump, wearing a red tie and dark suit, sat in the front row of the public gallery of the ornate courtroom after arriving by motorcade from the White House.The Republican president then left midway through the proceedings not long after the Justice Department lawyer arguing for his administration completed his presentation.Most of the nine justices, conservatives and liberals alike, grilled the lawyer with questions about the legal validity of Trump’s executive order and its practical implications. The court has a 6-3 conservative majority.US Solicitor General D. John Sauer, representing the administration, told the justices that most nations did not grant automatic birthright citizenship.“It demeans the priceless and profound gift of American citizenship,” Sauer said. “It operates as a powerful pull factor for illegal immigration and rewards illegal aliens who not only violate the immigration laws but also jump in front of those who follow the rules.”The United States is among 33 countries with automatic birthright citizenship policies, according to the Pew Research Center.
