Donald Trump attended a Supreme Court hearing on birthright citizenship, becoming the first sitting president to attend a court hearing. The president was hoping to hear favorable arguments in his effort to remove birthright membership, but left the court after listening to counterarguments from several members of the justices and some lawyers. After leaving the court, Trump called the United States "stupid" for allowing birthright Citizenship, a system that rewards illegal aliens and violates immigration laws. He is aiming to remove the right of thousands of babies granted citizenship to those born to non-identident parents in the US.
