The HUAC wasn’t McCarthy, of course; they are just sort of bound up in the same Red Scare history. It is routine for people outside the USA to conflate these things because of how they are presented in dramatisations; as a Brit I didn’t realise until recently.

McCarthy might have been a pivotal figure in McCarthyism (obviously ;-) but he had nothing directly to do with the HUAC because he was a senator.

He sat on what is now the Senate committee on Homeland Security and Governmental Affairs. It was the Senate Committee on Government Operations then, which had an enormously broad remit and gave him his ability to harass and persecute anyone who worked for the US federal government. He was also more able to resist pressure because of it.
