US Supreme Court has ruled President Donald Trump's travel ban on six mainly Muslim countries can go fully into effect. The ruling covers the third version of the directive that President Trump has issued since taking office. Yesterday, seven of the nine justices lifted injunctions imposed by lower courts on the policy. Only Justices Ruth Bader Ginsburg and Sonia Sotomayor would have allowed the President's order to remain blocked.<br/><br/>But the directive against travellers from Chad, Iran, Libya, Somalia, Syria and Yemen still faces legal challenges. Federal appeals courts in San Francisco, California, and Richmond, Virginia, will hear arguments this week on whether the latest iteration of the policy is lawful.<br/><br/>
