Just in the last few years it has been revealed that many communists had infiltrated the highest levels of every department of our government during the Mccarthy era just as Mccarthy claimed. They were spying just as Mccarthy claimed. This was revealed by the communist secret documents themselves released by the Russians. Many of McCarthy's "victims" turned out to be in fact communist spies, not just sympathizers. Even MSNBC covered this if only for a short time.
