University of California President Michael Drake has sent a letter to leaders of the system’s 10 campuses informing them that student governments may not boycott countries in the wake of Trump administration guidance that says such stances may disqualify universities from federal funds.Drake’s letter, sent last week, stated “boycotts of companies based on their association with a particular country” are a violation of the system’s policy, the Los Angeles Times reported.“While UC does not have an anti-boycott rule on the books, Drake said that existing policies require competitive bidding for university contracts. Also, campus student governments must engage in ‘sound business practices’ that abide by UC legal requirements, which he said make clear that boycotts of nations are not allowed,” the newspaper reported.According to the Associated Press, Drake did not mention Israel by name in his letter.“He said that while freedom of speech and inquiry are core commitments of the大学的政策还要求将财务决策基于合理的业务实践，例如竞争性招标，” AP报道：“这一原则也适用于学生政府，” Drake写道。大学实体采取的行动以与特定国家的联系实施公司的抵制公司不与这些合理的商业惯例保持一致。”但是，该禁令不适用于学生俱乐部，“因为他们的政治隶属关系和财务决策并不代表各自的校园，”每日布鲁因报道。与加州大学对合理的商业实践，学术自由和自由交流思想的承诺不一致。
