Meringolo’s distinguished legal career as a practicing attorney and professor of law has earned him a reputation as an expert in federal criminal practice.  He frequently provides expert commentary for periodicals such as the Daily Beast, New York Post and the New York Daily News.

On March 26, 2019, the New York Post recognized Meringolo’s recent back-to-back acquittals against Manhattan federal prosecutors and quoted him regarding attorney Avenatti’s claims of innocence in the face of serious criminal charges. Meringolo observed that “he may want to take the stand at one point. He’s giving the government cross-examination material.”

On March 8, 2019, Meringolo commented in the New York Post on the death of Carmine “The Snake” Persico’s death. Drawing on his extensive experience representing reputed Mafiosos, Meringolo commented that “he’s from the bygone era from when organized crime controlled New York City. It was a part of history, just like Al Capone and Jesse James.” said Pace University law-school Professor John Meringolo, who’s repped reputed Mafiosos.

On January 17, 2019, Meringolo weighed in on embroiled Harvey Weinstein’s search for new defense counsel and reported desire to put together a “dream team” of lawyers. “It’s definitely not smart to do that as you need to develop rhythm during trial, potentially pitting witnesses against each other. If attorneys are doing different witnesses and different aspects, the lead attorney may not know what's going on. It’d be like having two separate quarterbacks in a football match.”

On May 14, 2018, the New York Post reported on the US Supreme Court’s sports-betting ruling. Noting that Meringolo hadrepresented John “Junior” Gotti and reputed Philadelphia mob boss Joseph “Skinny Joey” Merlino, the paper quoted Meringolo as opining that the ruling “will have a detrimental effect on the mob and anyone who tries to make a living through this type of vice. For what’s left of what they do, this would significantly hurt their bottom line, if not completely destroy it.”

On November 26, 2015, Meringolo provided commentary to the New York Post regarding jury deliberations in the trial of former Speaker of the New York State Assembly, Sheldon Silver. Meringolo “said his experience suggested the juror was holding out… When there’s chaos in the jury room, it’s always good for the defendant. Statistically, the conviction rate is so high in the federal system, when you have someone willing to take a stand, it means that maybe he’s got a shot.”

On September 17, 2015, the New York Daily News relied upon Meringolo’s expert opinion in an article about the trial of Vincent Asaro, the alleged mobster charged in the Lufthansa heist portrayed in the motion picture Goodfellas. “It’s very rare for a crime to be depicted in a movie or a book before the trial is held,” Meringolo told the Daily News, also referring to the book Wiseguys by acclaimed journalist Nicholas Pileggi, which inspired the film. Meringolo also advised that “the gangland bloodbath depicted in the Goodfellas film in the aftermath of the Lufthansa robbery would be highly prejudicial to Asaro because he was not involved with killing any of the members of the crew.”

On June 6, 2017 the New York Post reported that reputed Mob Boss Joey Merlino hired John Meringolo.  The Post opined that Merlino hired Meringolo, a “big shot lawyer” “who has represented former Gambino boss John ‘Junior’ Gotti and acting capo Greg DePalma” because he was “gearing up for battle in a massive racketeering case brought by Manhattan federal prosecutors, turning down a sweet deal from the feds.”  On February 20, 2018, a federal judge in Manhattan declared a mistrial in Merlino’s case  – a case that threatened to send him back to prison for decades.
