Thirty-five organizations representing a wide range of health care professions and medical specialties yesterday filed an amicus brief urging the Supreme Court to affirm the decision of the Ninth Circuit and maintain the injunction against a presidential proclamation last September that restricted travelers from certain countries entering the United States. “The proclamation’s presumptive barring of physicians and other highly skilled scientists and health professionals solely on the basis of nationality will likely have an adverse impact on the ability of teaching hospitals and research universities to recruit and retain needed members of their health-professional and scientist workforces,” state the groups, including the Association of American Medical Colleges.
