The US Justice Department has asked the Supreme Court to block a judge's ruling that prevented President Donald Trump's travel ban from being applied to grandparents of US citizens and refugees already being processed by resettlement agencies.<br/><br/>In a court filing, the administration asked the justices to overturn Thursday's decision by a U.S. district judge in Hawaii, which limited the scope of the administration's temporary ban on refugees and travelers from six Muslim-majority countries. <br/><br/>District Judge Derrick Watson yesterday ordered Homeland Security and the State Department not to enforce the ban on grandparents, grandchildren, brothers-in-law, sisters-in-law, aunts, uncles, nieces, nephews, and cousins of persons in the United States. <br/><br/>The Supreme Court's decision last month revived parts of President Donald Trump's March 6 executive order banning travelers from Iran, Libya, Somalia, Sudan, Syria and Yemen for 90 days, as well as refugees for 120 days.<br/><br/>
