Is it true that Senator Joseph McCarthy won national attention when he accused Professor Owen Lattimore with being a top Soviet Spy?

Yes, Senator Joseph McCarthy gained national attention in the early 1950s when he accused Professor Owen Lattimore of being a top Soviet spy. Lattimore was a prominent scholar in Asian studies, and McCarthy's allegations were part of his broader campaign against alleged communists in the U.S. government and society. The accusations against Lattimore, however, were largely seen as unfounded and contributed to the climate of fear and suspicion during the Red Scare.
