Ismail Elshikh, an American citizen from Egypt, joined the state of Hawaii in lodging the first challenge to US President Donald Trump’s executive decision to restrict entry to refugees and travelers from six Muslim-majority countries. The state says Elshikh, an Imam at the Muslim Association of Hawaii whose mother-in-law lives in Syria, is being subject “to discrimination and second-class treatment” along with his family and members of his mosque. The state is arguing the ban violates the constitution, Reuters reports.
