The law professor who spoke during President Donald Trump's Washington, D.C., rally before the attack on the U.S. Capitol has retired from a California university where there were demands for his ouster. Eastman's retirement resulted from an agreement reached during discussions and was effective immediately, university President Daniele Struppa said in a statement to the school community Wednesday.
