The battle between Nassau County and Hofstra University appears to be heating up beyond the legal action between the two. County Executive Bruce Blakeman says he has subpoenaed Hofstra president Susan Poser, accusing her of colluding with a competing casino organization in an effort to derail plans by Las Vegas Sands to redevelop the Nassau Coliseum.

In a news conference Wednesday, Blakeman shared with reporters an email he says was sent by Michael McKeon — who he described as a lobbyist for Florida-based Hard Rock Café Inc. — to a Hard Rock senior vice president, Sean Caffery, as well as Michael Sullivan, who works for an asset management company purportedly connected to New York Mets majority shareholder and Hard Rock International partner, Steven Cohen.
