Most people objected to McCarthy anti-communist work not because of his claims of communist activity in America but rather his methods of investigation. He rarely offered anything approaching proof of subversion or treason. Typically, what he offered as proof was the admission of a person attending a communist meeting, a person associating with a know communist, hearsay evidence at party or a private conversation, or a newspaper article that names a person a communist.On the 141st birthday of President Abraham Lincoln, on February 12, 1950, Senator McCarthy passionately said:
'The reason why we find ourselves in a position of impotency is not because our only powerful, potential enemy has sent men to invade our shores, but rather because of the traitorous actions of those who have been treated so well by this nation…. This is glaringly true in the State Department. There the bright young men who are born with silver spoons in their mouths are the ones who have been worst…. In my opinion the State Department, which is one of the most important government departments, is thoroughly infested with communists.'
J.Egard Hoover worked very closely with Joe McCarthy and supplied him with most of the information McCarthy used to expose the massive scale of Soviet espionage in America.
Hoover got much or most of his informtion from the Venona Intercepts and at that time that operation was Top Secret and neither Hoover nor McCarthy could reveal the source of their information.
McCarthy and Hoover were up against the political establishment in Washington which used it's power to destroy McCarthy.
To this day the Senator is still attacked and demonized although the Venona Project is now known to the public and it reveals that McCarthy was right.

M. Stanton Evans has written a Human Events column, “When Conservatives Parrot Liberal Lies about Joe McCarthy,” about how various conservative media personalities and politicians, including former Tennessee Republican Senator Fred Thompson, writers at Breitbart.com, National Review’s Rich Lowry and columnists/TV commentators Charles Krauthammer and George Will, have all used the term “McCarthyism” to refer to the antics of Harry Reid and others on the left. Evans writes that these conservatives “know nothing at all about McCarthy except what the liberals deign to tell them.

It's Time to See Joe McCarthy For the Hero He Was
When McCarthy named over 200 state department people as communist he immediate got Hoover's attention. For a time Hoover did work with McCarthy but if became clear to Hoover that McCarthy was grandstanding. Hoover made his position clear. "Don't label anyone as a Communist unless you have the facts," he wrote in Newsweek. "Don't confuse liberals and progressives with Communists. Don't be a party to a violation of the civil rights of anyone. When this is done, you are playing right into the hands of the Communists."
