And who was the President that signed the executive order that interned Japanese-Americans?
That's right: Franklin D. Roosevelt, the liberal hero.
And who was Attorney General and then Governor of California during WW2, whose influence was essential in establishing the internment camps?
That's right: Earl Warren, the liberal hero.
"A liberal Republican, Warren was elected California attorney general in 1938. Though he helped to modernize the office during his term, Warren's record was tarnished by the fact that he was a key player in the demand that
people of Japanese ancestry be removed from the West Coast during
World War II. Warren and others justified their actions by insisting that it was a matter of national security, and that California was vulnerable to Japanese spies. The
U.S. Supreme Court upheld the removal in
Korematsu v. United States (1944). Thousands of Japanese Americans lost their property and businesses, and were moved to concentration camps for the remainder of the war. Warren defended his actions throughout his public career, but in retirement, he admitted the relocation was a terrible mistake based on unsubstantiated fears."
