(Bloomberg) -- Four big hedge fund managers contributed a total of $2 million to a political action committee supporting Brooklyn Borough President Eric Adams, who is leading in some polls for the Democratic primary for New York City mayor.Billionaires Ken Griffin, Dan Loeb, Stanley Druckenmiller and Paul Tudor Jones donated to Strong Leadership NYC Inc., which spent about $1.2 million on a television ad for Adams, who is running on a tough-on-crime platform. The committee, which can spend unlimited amounts on the race as long as it’s not coordinating with the Adams campaign, was set up by Jenny Sedlis, the executive director of StudentsFirstNY, a group that backs charter schools.Adams, who retired at the rank of captain from the New York Police Department after a 22-year career, initially made his mark as a police reformer. He is campaigning ahead of the June 22 Democratic primary on a violence crackdown, saying he wants to create a controversial plainclothes anti-gun unit similar to an anti-crime unit that was disbanded after it generated a disproportionate share of complaints and instances of excessive force.Read More: NYC Mayoral Hopeful Adams to Restore Controversial Anti-Gun UnitRead More: NYC’s Crime Spike Puts Policing in the Spotlight of Mayor’s RaceSpokespeople for Griffin, Loeb, Druckenmiller and Tudor Jones didn’t provide immediate comment.With about a month left before the June 22 Democratic primary, Super-PACs backed by wealthy individuals, corporations and labor unions are pouring cash into a race that has been described as the city’s most consequential in a generation.
