It was clear message from some ‘serious people’ that you don’t go to war with the people who put you in power.

No kidding. Giancana and Company got him elected after which JFK sicced his little brother on organized crime. What a dumbass.

I remember these hearings from the mid-to-late 1950s.

From Internet sources: ". . . [Robert] Kennedy asked to be Chief Counsel on a new Committee led by [Senator] McClellan that would investigate organized crime in America. Joining Bobby Kennedy on this Committee would be his brother, Senator John F. Kennedy of Massachusetts. The McClellan Committee became a national obsession, with Bobby Kennedy the star during televised hearings in which Kennedy grilled leading Mafia figures of the day, most of whom repeatedly invoked their Fifth Amendment rights against self-incrimination. Bobby Kennedy taunted his adversaries relentlessly; during one such grilling of Chicago Mob Boss Sam Giancana, the wiseguy erupted into a nervous giggle, prompting Bobby Kennedy to taunt: 'I thought only little girls giggled, Mr. Giancana!'"
