Florida prosecutors in the Robert Kraft prostitution case have alleged two of the billionaire Patriots owner’s attorneys lied in court.

But the lawyers William Burck and Alex Spiro fired back on Wednesday: “Unable to justify a lawless, indefensible prosecution on its merits, the State has resorted to trying to smear defense counsel.”

It’s just the latest twist in an increasingly contentious case in which Kraft has been accused, with dozens of other men, of soliciting prostitution at the Orchids of Asia Day Spa and other massage parlors.

Kraft’s pleaded not guilty.

This week, the Palm Beach, Fla., State Attorney’s Office filed papers alleging Kraft’s lawyers, Spiro and Burck, intentionally made a false statement of fact at a recent hearing on Kraft’s motion to suppress video evidence in the case.

While questioning a Jupiter police officer, Scott Kimbark, Spiro accused Kimbark of telling other officers he would make up a reason to stop a customer who left the Orchids of Asia Day Spa directly before Kraft in January.

But Kraft’s attorneys said in their legal response, “It is undisputed that Officer Kimbark referred specifically and expressly to his plan to ‘come up with something’ as his claimed basis for making the relevant vehicle stop.”
