Edited sentence: Also, in 1956, several years before he targeted King, Hoover had a public showdown with T.He had protested against California Governor Earl Warren's plan to intern Japanese-Americans during WWII and  took strong action against the Ku Klux Klan in the 1950's as part of CONTELPRO.Hoover did not like to be portrayed as racialy biased.Hoover not only wrote an open letter to the press singling out these statements as "irresponsible" but secretly enlisted the help of NAACP attorney (and later Supreme Court Justice) Thurgood Marshall in a campaign to discredit Howard, which was given by Marshall.It is more likely, however, that it was King's failure to purge Communists from his supporters' ranks that drew Hoover's interest.Some think these actions reflected the biases and prejudices of the country at large, especially in the attempts to prevent Martin Luther King, Jr
