A top Department of Justice spokesman in New York was caught on a hidden camera ripping Manhattan District Attorney Alvin Bragg for his recent prosecution of former President Donald Trump — accusing Bragg of conducting “lawfare” just to further his own political ambitions.

Nicholas Biase, chief spokesman for the Manhattan US Attorney’s Office, was secretly recorded tearing into the progressive prosecutor during a recent conversation with a so-called undercover operative from conservative podcaster Steven Crowder’s “Mug Club.”

“Honestly, I think the case is nonsense,” Biase was filmed saying to an unidentified woman on July 31 at what appears to be a bar.

The edited clip, and another from August 14, were released by Crowder on social media Thursday. The identity of the woman who secretly recorded the exchange with Biase wasn’t made public. The Post has not reviewed the full, unedited recordings.

Biase — who said he’d known Bragg for 15 years and previously worked with him at SDNY — described the unprecedented hush money case against Trump as a “perversion of justice” in the footage.

He also claimed the headline-grabbing prosecutor pursued the case to make a name for himself and run for higher office.

“He wants to be, something … a mayor? I’m not sure what he wants to be, but I know he’s not happy just being the DA of New York County. Before he decided to prosecute Trump, did you know who he was? You do now,” he said in the clip.

An apologetic Biase told The Post in a statement Thursday that he made the remarks in a private setting with someone he’d “just met” and was trying to “impress.”

At one point in the video, Biase accused Bragg of “stacking charges [against Trump] and, like, rearranging things just to make it fit a case.”

Trump, who was convicted on 34 felony charges of falsifying business records over payments made to a porn star ahead of the 2016 election, is set to be sentenced on Sept. 18.

“This guy is probably going to try to lock him [Trump] up. And there is going to be, it’s going to be ugly…,” Biase said, in an apparent reference to Manhattan Supreme Court Judge Juan Merchan, who is overseeing the case.  

“They are so obsessed with getting him [Trump],” he continued.

Asked whom he meant by “they,” Biase shot back: “The Democrats … It affects his candidacy if he’s a convicted felon.”

But the spokesman said the apparent ruse backfired.

“Those felonies did nothing to stop Trump from running … In fact, they made him [Trump] more relevant,” Biase said in the recording.

Later, Biase appeared to refer to Trump’s separate civil fraud case brought by state Attorney General Letitia James, in which the ex-president was found guilty of inflating the value of his assets to get bank loans.

“Every real estate person in New York does what he [Trump] did. Nobody’s ever been charged with this … You know, it’s a perversion of justice,” he was filmed saying.

Biase also railed against state-level justice systems as a whole, describing it as “the Wild West.”

“At the federal level, where I work, there is a 90-day rule where you can’t make any decisions on cases that are going to affect an election [within 90 days of an election],” he said.

“That rule does not apply at the state level because the state level is like the f–king Wild West … They are like idiots. They don’t care. They’re all political.”

Elsewhere, Biase described another state-level prosecution of Trump by another elected Democrat, District Attorney Fani Willis of Fulton County, Georgia, as a “travesty of justice.”

Trump and 18 co-defendants were indicted last year on charges of conspiring to overturn the 2020 election result in the Peach State.

“To put it mildly, it’s a mockery of justice. She is a joke … The whole thing is disgusting. They’re just out to get him [Trump],” Biase said of Willis.

Biase has since apologized for the remarks, telling The Post on Thursday he “should have known better.”  

“I was recently made aware of a video where I regretfully made some statements in a private and social setting that don’t reflect my views about two local and state prosecutions,” he said in a statement.

“I said these things in an effort to please and impress someone I just met, who was secretly filming me. I’m deeply sorry to the local and state law enforcement officials working on these matters, who deserve more respect than I showed them.  I should have known better.”

Biase was promoted to his current role in 2021 by Manhattan US Attorney Damian Williams.

At the time, Williams described him as a “vital liaison for an office in the media capital of the world [and] a trusted counselor and confidante to every US attorney he has served.”

Williams went on to say Biase was “respected by the press corps for his professionalism, integrity and candour.”

The Post reached out to the Manhattan DA’s Office about the secret recording, but didn’t hear back immediately.
