Prof. Sanford Jacoby - in a Facebook post - points to a state-funded travel ban that applies to UC:

PROHIBITION ON STATE-FUNDED AND STATE-SPONSORED TRAVEL TO STATES WITH DISCRIMINATORY LAWS (ASSEMBLY BILL NO. 1887)

In AB 1887, the California Legislature determined that "California must take action to avoid supporting or financing discrimination against lesbian, gay, bisexual, and transgender people." (Gov. Code, § 11139.8, subd. (a)(5).) To that end, AB 1887 prohibits a state agency, department, board, or commission from requiring any state employees, officers, or members to travel to a state that, after June 26, 2015, has enacted a law that (1) has the effect of voiding or repealing existing state or local protections against discrimination on the basis of sexual orientation, gender identity, or gender expression; (2) authorizes or requires discrimination against same-sex couples or their families or on the basis of sexual orientation, gender identity, or gender expression; or (3) creates an exemption to antidiscrimination laws in order to permit discrimination against same-sex couples or their families or on the basis of sexual orientation, gender identity, or gender expression. (Gov. Code, § 11139.8, subds. (b)(1), (2).) In addition, the law prohibits California from approving a request for state-funded or state-sponsored travel to such a state. (Gov. Code, § 11139.8, subd. (b)(2).)

The travel prohibition applies to state agencies, departments, boards, authorities, and commissions, including an agency, department, board, authority, or commission of the University of California, the Board of Regents of the University of California, and the California State University. (Gov. Code, § 11139.8, subd. (b).)

The law also requires the Attorney General to develop, maintain, and post on her Internet Web site a current list of states that are subject to the travel ban. (Gov. Code, § 11139.8, subd. (e).)
