CSU Chancellor Mildred Garcia said Lee "has informed me of his decision to retire," Xinhua news agency reported. She called Lee's action "insubordination" and named an acting president on Thursday. .

“The heart and mission of CSU is to create an inclusive and welcoming place for all we serve, not to segregate one community from another,” Garci said in a statement Thursday.

Lee reached an agreement with pro-Palestinian students who had set up tents on the school's campus. He publicly apologized on Wednesday evening and said he acted without the approval of CSU leaders.

Lee had been president of Sonoma State University for less than two years after serving as an administrator and business professor at Sacramento State University for 28 years.
