Actually, one of the theories out there is that DiMaggio went to the Mafia to have JFK killed.

It was well-known that DiMaggio and Kennedy didn't get along because of the whole Marilyn Monroe saga.

In fact, one Opening Day at Yankee Stadium, Kennedy threw out the ceremonial first pitch. On his way off the field, he walked past all the Yankees, who were lined up in front of the dugout. While all the other ballplayers shook JFK's hand, DiMaggio wouldn't even look at him.

It's hard to imagine that DiMaggio didn't have at least some ties to the Mafia.

Pretty much every Italian has a connection if they look hard enough. And Italians as famous as Joltin' Joe at least had the opportunity.
