No, FDR signed an executive order creating the internment camps, not the governor of California.
I didn’t use the word “governor” in my post:
As Attorney General, Warren is most remembered for being the moving force behind Japanese internment during World War II. This was the compulsory removal of 120,000 Americans of Japanese descent from the West Coast to inland internment camps, without any charges or due process - when anti-Japanese racism was extremely popular in California. Following the Japanese Attack on Pearl Harbor in December 1941, Warren organized the state’s civilian defense program, warning in January 1942 that, “The Japanese situation as it exists in this state today may well be the Achilles heel of the entire civilian defense effort.”[11][12] He later said he:
since deeply regretted the removal order and my own testimony advocating it, because it was not in keeping with our American concept of freedom and the rights of citizens...Whenever I thought of the innocent little children who were torn from home, school friends, and congenial surroundings, I was conscience-stricken...[i]t was wrong to react so impulsively, without positive evidence of disloyalty
